2021 with MEI

"It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of light, it was the season of darkness, it was the spring of hope, it was the winter of despair.”

Very prescient of Charles Dickens in his introduction to A Tale of Two Cities, which sums up this year, with its promises of better things to come followed by depressing set backs.

In last year's annual summary I ended by saying that we must put our faith in the amazing efforts of the scientists and their vaccines and hope for better things to come in 2021, as another highly contagious strain, emanating from South Africa, had been identified, escalating restrictions. Twelve months later restrictions have again been tightened with the emergence of another mutant strain of the awful Coronavirus, Omicron, also emanating in South Africa.

When will this ever end? We had got used to endless globe-trotting, meeting up with old friends, getting to know new people and visiting interesting places, and personally I will remember 2021 as the first year since 1979 that I have not left the UK. In fact Barbara and I have only left Cornwall once this year, for a week in beautiful Dorset (posting of 23 September)

It was a grim start to the new year with the new variants of Covid-19 threatening to spread across the country and savage the beleaguered NHS, and Prime Minister Boris Johnson announced a complete lockdown of the UK. Travel into and out of the UK became virtually impossible as most of the travel corridors with the UK were suspended and, coupled with Brexit, Britain became, for the first time in its history, an effectively isolated nation. A month later with the vaccine roll-out initiated, and over 15 million people in UK having had their first jab, Johnson announced that we were past the peak of the 2nd wave and "the crocus of hope is poking through the frost and spring is on its way..." It's never good to predict the future! 

At the end of February twelve months had passed since I last boarded a plane, a flight from Phoenix to London Heathrow at the end of the SME Annual Meeting. This year's scheduled meeting in Denver became an online event and I missed not being in my favourite American city to see the Mineral Processing Division's award winners, three old friends of MEI, Prof. Courtney Young, Dr. Frank Crundwell and Dr. Michael Mankosa (posting of 8th March 2021). 

MEI's four conferences this year have all been online events, and I must say how immensely proud I am of Jon and Amanda who accepted the challenge of converting our scheduled meetings to virtual events. Apart from advising on the technical programmes I have had little input and I am pleased to see MEI now being slowly shifted to the next generation.

The conferences have been well received and the advantage of the online events is that the recorded presentations for Comminution '21, Biomining '21, Sustainable Minerals '21 and Flotation '21 are now available on demand.

I would also like to say that we are tremendously indebted to our sponsors, old and new, who have supported our conferences during these difficult times:


It was good to socialise again in May, with relaxing of restrictions, and the first Cornish Mining Sundowner of the year was held on a chilly evening on Falmouth's Gyllyngvase Beach, followed by further outdoor meetings in Falmouth.

The super-spreader G7 summit in Cornwall in June (posting of 1st July), and a huge influx of summer visitors caused a rapid rise in Coronavirus infections in Cornwall, which soon had the country's highest infection rate, but by September with the crowds dissipating so did the infection rate and with social distancing no longer mandatory we had a welcome return to the Chain Locker pub in September and the CSM Annual Dinner in October, after an enforced break of two and a half years.

Apart from running the online conferences, Jon and Amanda have been busy with voluntary work, Jon working in a local hospice shop and Amanda as a Mabe Parish Councillor as well as a mentor for a charity supporting people affected by domestic abuse and sexual violence.

They raised money for these charities by taking part in tough long-distance cycling and hiking events.

gruelling 104 miles, 7 and a half hour Coast to Coast Extreme Route Challenge in Cornwall

Barbara and I had some good hikes during the summer, including the challenging short walk over southern England's highest cliff, Golden Cap in Dorset (posting of 9 September), but our first hike of the year, at Coverack on Cornwall's Lizard Peninsula ended abruptly when I slipped on the very muddy coast path and fell down the cliff, fortunately tangling in painful brambles which prevented a long drop to the rocks below.

Avoid the Cornish coastal path after heavy rain!!

Conditions were much better in October for a 50 year reunion with an old friend from Zambia days, Pete Love, and his wife Pam, who stayed with us for a few days.

And so ends another year of uncertainties, and who know what the next will bring. On behalf of the MEI team I wish you all best wishes for 2022. We had a final 2021 family get together yesterday in St. Agnes and it was great to welcome Flo (right on photo) the girlfriend of 17 year old William. Flo's grandfather, Bob Wyatt, was an international cricketer, captaining the England Test team 15 times, and was vice-captain to Douglas Jardine on the infamous 1932-33 'bodyline' tour of Australia.  The current England test team touring Australia are in need of a few batters of Bob Wyatt's calibre at present!

Happy New Year to you all.

The Queen's address to the nation- and that magnificent sapphire brooch

It is now over 40 years since I met the Queen at Camborne School of Mines, and there was much interest then in the beautiful sapphire brooch that she wore. 

Meeting the Queen at CSM in 1980

Yesterday there was intense media interest in the same brooch, which she wore for her annual Christmas Day message. The framed photograph in view during the broadcast was taken during the diamond anniversary of her and Prince Philip, who died this year after 73 years of marriage. She also wore the same brooch, in the form of a chrysanthemum, on their honeymoon in 1947.

I remember the CSM geologists in 1980 speculating on the value of the brooch, the sapphire being surrounded by 12 large diamonds, and today the brooch is estimated to be worth around £8-9 million, thanks also to its historic provenance. It dates back to the 1800s, Prince Albert giving the brooch to Queen Victoria on their wedding day in 1840. 

During her address the Queen highlighted the importance of "passing the baton" to the next generation, something relevant and ongoing at MEI since we adapted this year to online conferences. There are more baton passes scheduled for 2022 when we hope to progress to hybrid events. Let's hope that the world is a better place by then.

Season's Greetings from MEI

Photo: Tony Clarke

This time last year I wrote "By any standards 2020 has been an awful year, but as it draws to a close we hope that 2021 will lead us back along the road to normality".

Unfortunately 2021 has not done that and the pandemic still rages on.  However we must be optimistic, and whether you celebrate Christmas or not we would like to wish you all sincere best wishes for the holiday season and hopefully better things for 2022. And a big thank you to all of you who have sent us Christmas greetings by email.

The critical need for accelerating innovation in the mining sector

The mining sector is facing many challenges in delivering minerals to market given rise in demand, especially for key renewables related mineral supply. Some of the greatest challenges are reflected in the difficulties around getting permits and the social licence to operate especially given climate change and the energy intensity of the mining industry. Accelerating innovation and collaborating together has never been so critical. Open innovation systems are more important than ever to achieve this, which is why MEI has initiated a new conference, Integration, Optimisation & Design of Mineral Processing Circuits (IntegratedMinPro '22).

Australian company Gekko Systems has always had a particular focus on reducing energy intensity and increasing energy efficiency. This has resulted in a focus on new flowsheets, pre-concentration, reducing treatment of gangue/waste, utilising low energy technologies as well as being instrumental in the establishment of not-for-profit CEEC – the Coalition of Eco-Efficient Comminution, an industry advocate for IntegratedMinPro '22, and other MEI Conferences. We are therefore delighted to announce that Elizabeth Lewis-Gray, co-founder and Chair of Gekko Systems and Founder and Patron of CEEC will be presenting a keynote lecture at IntegratedMinPro'22

Elizabeth has been a strong advocate for innovation, collaboration and the METS Industry for almost two decades with long serving roles on the Board of Austmine (including Chair), CSIRO’s Mineral Advisory Board and the Federal Government’s Innovation Australia Board. Her own business, Gekko Systems, is a world leader in gold and silver processing technology, consulting, and energy efficient modular processing solutions.

Elizabeth is a Fellow of the Academy of Technology Science  and Engineering and the Australasian Institute of Mining and Metallurgy (FAusIMM). In addition she is the recipient of an Honorary Doctorate from Federation University for services to mining and a recipient of Australian 100 Women of Influence Awards and the Warren Engineering Innovation Heroes Award (see also posting of 16 March 2015).

In her keynote lecture "The critical need for accelerating innovation in the mining sector" Elizabeth will show how, increasingly, mining companies are looking to reduce their energy footprint and to utilise renewable/low carbon energy sources which will place further pressure on designing low energy and flexible mineral processing facilities.

The capacity to successfully deliver new innovation is still problematic for the mineral processing sector and mining industry which still has many barriers including high capital investment risk, low risk profile of engineers by nature, influence of investors, etc. Many mineral processing flowsheet designs are designed to minimise risk not energy. Timelines/budgets no longer allow for pilot studies. 

The sector must find new pathways to accelerate collaboration, knowledge sharing and innovation and a number of new pathways to market are being trialed and established. However, it is also critical for the innovation to take place across the whole value chain of mining to eliminate waste and maximise efficiency – including accessing and sharing data across the pillars of geology, mining and metallurgy.

The keynote will truly reflect the theme of the conference which invites abstracts on new approaches to mineral processing circuits, whether through design, modelling, optimisation or operation. This includes integration of unit operations (e.g. comminution and flotation), novel flowsheets that incorporate new equipment and new approaches to optimising circuit design.

Christmas Cornish Mining Sundowner in Camborne

It is two years now since our last Christmas Cornish Mining Sundowner at Tyacks Hotel in Camborne, so it was good to be back there last night, despite Covid cases in UK soaring again thanks to the latest variant Omicron. Cornwall's infection rate is now below the country's average and there has so far been only one recorded Omicron case in Cornwall. The epicentre is London so we took the chance last night before the mutation crosses the Tamar into Cornwall and followed the Governments 'clear' advice to "socialise carefully".

I doubt if anyone who has been associated with Cornish mining has not heard of Tyacks, situated in the centre of Camborne, itself once the epicentre of the world's copper and tin mining industries.

Established in 1780 the hotel is only a few yards from the site of the original Camborne School of Mines (CSM), and was frequented by local miners from South Crofty and Pendarves and CSM students and staff. Once CSM moved to Pool, between Camborne and Redruth, in 1975 and CSM had its own club behind the old CSM building, students frequented Tyacks less and less and after the move to Penryn in 2004 I doubt if many of the current students have even heard of Tyacks.

The original CSM in the centre of Camborne

The old inn is steeped in atmosphere, as is our summer sundowner location, Falmouth's Chain Locker. But whereas the Chain Locker reflects Falmouth's nautical heritage, Tyacks highlights the area's rich mining history, and dotted all around the pub are pictures of Camborne's most famous mining engineer, Richard Trevithick (posting of 25 April 2015) and photos by arguably the 19th century's most accomplished mining photographer, also a Camborne man, J.C. Burrow (posting of 25 May 2015).

The Christmas sundowner is always the most popular, and despite the pandemic we had over 30 in attendance last night.

It was good to see Treve and David Mildren, of local company Gravity Mining Ltd. The company is the home of the original Mozley Multi Gravity Separator (MGS) and yesterday they agreed to sponsor MEI's Physical Separation '22 next year.

and Nigel MacDonald of King Edward Mine Museum

The Sundowner was a great opportunity to recognise the achievements of one of our regulars, Robin Dunn. Robin has contributed 35 years in various roles at CSM but his links to CSM actually go back to 1963. He  retired in April 2020 just at the start of the pandemic so tonight was a much delayed ‘few beers in Tyack’s’  that he said he would be happy with. 

Robin played a key role supporting the Principal, Dr. Peter Hackett in 1992/93 when CSM was saved from certain closure by merging into the University of Exeter and also saving the University's Engineering in the process. 

Robin was Clerk to the Trustees of the CSM Trust  and managed the finances in a way that has allowed over £3 million pounds to be donated to support Mining and Minerals Education, an extraordinary achievement.    

The Trust was keen to maintain the links to Camborne so Robin worked to preserve the Memorial Rugby Ground, developing a relationship with Camborne Rugby Club to use and maintain the ground. Ultimately the Ground was dedicated as a Field in Perpetuity which now means that Camborne Rugby Club and the CSM Memorial Ground can never be built over.

Last night Camborne Rugby Club presented Robin with a Gold Pass in recognition of the his efforts to secure the links with CSM. The Gold Pass was presented by Bill Hussey of Camborne Rugby Club, himself an ex CSM student. CSM Trust Chairman Dr. Tony Batchelor, ably assisted by Matt Colwill, the current CSMT Clerk to the Governors, and Carol Richards  of the Camborne School of Mines Association, presented Robin with South Crofty tin cuff links, tiepin and replica Cornish coins and tokens as well a particular vintage port Robin had requested. Finally Tony announced that a fund had started to raise money for a contribution to cruising/travel, which Robin really loves, when Covid allows; over £1200 had already been pledged and the fund had not yet been announced.  Worthy recognition indeed for a true friend of CSM, surrounded by many of his old friends.

and Andy Gill, Chairman of Camborne Rugby Club

The Tyacks sundowner lived up to all its usual expectations, and we now hope that we can all get together next month for the January sundowner, which is scheduled to be held at the County Arms, Truro, on Thursday January 20th.

We welcome Weir Minerals as a sponsor of Sustainable Minerals '22

Global company Weir Minerals delivers wear, corrosion and abrasion resistant engineered products for heavy duty slurry pumping, industrial processing and control applications. The company last sponsored an MEI Conference nearly 10 years ago, Comminution '12 in Cape Town.

It is great to have them involved with MEI again as a sponsor of Sustainable Minerals '22, joining ZEISS, Metso Outotec, Promet101 and Hudbay Minerals as major sponsors, and our Media Partner International Mining, and Industry Advocates the Coalition for Eco-Efficient Comminution (CEEC), the Cornwall Mining Alliance and the Critical Minerals Association.

There is a call for abstracts for the conference, which should be submitted by the end of April.

And a reminder that registration is still open for Sustainable Minerals '21, which was held in July. Recordings of the presentations and the panel discussion are available on demand. Brief summaries of each day's proceedings can be found here.

Things are happening at Cornish Lithium

The uncertainty regarding the Omicron variant is having a marked effect on Christmas celebrations, and tonight Barbara and I should have been in Truro for the Cornish Lithium Christmas party, which has been cancelled, as it was last year due to the pandemic.

A great pity as I was looking forward to congratulating Dr. Lucy Crane, firstly on recently becoming a mum, and on her excellent presentation on the importance of mining at last month's Conference on Critical Minerals and The UK’s Green Industrial Revolution. This forum was organised by the Geological Society Business Forum, Institute of Materials, Minerals and Mining (IOM3) and MEI Conferences' industry associate the Critical Minerals Association.

It would also have been good to talk to Cornish Lithium's CEO and Founder, Jeremy Wrathall on his appointment to the UK’s Critical Minerals Expert Committee, together with a select number of industry and academic experts.

The formation of the Committee is a key element of the UK Government’s Net Zero Strategy  and is the first of its kind in the UK, to provide independent advice to government on the scope and content of a critical minerals strategy. The Committee will also define and publish an updated list of these minerals to guide government investment decisions. The resulting UK Critical Minerals Strategy will be published in 2022, setting out the UK’s approach to securing the technology critical minerals and metals. Through this strategy, the UK government will seek to support the engagement of the UK’s mining sector in new and existing markets, facilitating investment and collaboration in extraction and processing opportunities.

Jeremy and Lucy at the last Cornish Lithium Christmas Party in 2019

Cornish Lithium is pushing forwards with developing a sustainable domestic source of lithium for the benefit of the UK. Last month the company secured £18m of funding from Investment company TechMet, which will help fund Cornish Lithium’s plan to establish a UK-based supply of battery metals used in EVs.

Cornish Lithium said the UK needs an estimated 75,000 tonnes of lithium carbonate equivalent by 2035 to meet growing demand. By comparison, in 2020, Portugal – Europe’s largest lithium producer – produced about 1,200 tonnes of lithium. The UK government has made the extraction and supply of minerals such as lithium a priority and Cornish Lithium called the funding from TechMet “transformational”, adding that it would “significantly accelerate” its projects.

This will allow further drilling of geothermal evaluation boreholes and developing associated direct lithium extraction sites to further demonstrate Cornwall’s prospectivity for lithium contained in geothermal waters (posting of 18 September 2020). The Company will also progress studies into the possibility of using heat from these boreholes to decarbonise local industries in Cornwall.

The funding will also aid the construction of a beneficiation and hydrometallurgical demonstration plant that will enable the Company to optimise the low carbon Lepidico processing technology for the Trelavour Project (posting of 10 December 2020) for the extraction of lithium from zinnwaldite and polylithionite mica ores in the St Austell region. Only a wek ago Cornish Lithium announced the Maiden JORC Resource Statement for The Trelavour Project.

Hopefully there will be much to report in 2022!

International Mineral Processing Congress 2022 is cancelled

As a media partner MEI was sad to hear that the IMPC Council, working closely with AusIMM, has announced that the XXXI International Mineral Processing Congress 2022 (IMPC 2022) in Melbourne will be cancelled.

In the face of ongoing uncertainties around border closures and travel restrictions, and the acknowledged impact this will have on hosting a global event, postponing the Congress honours IMPC’s commitment to driving immersive knowledge sharing across all facets of mineral processing innovation. 

With this announcement, numbering for future IMPC events will adjust accordingly. As a result, the next event in the series, to be held in Washington DC in 2024, will be titled the XXXI International Mineral Processing Congress. The last IMPC was held in Moscow in 2018, the subsequent IMPC 2020 in Cape Town also being cancelled due to the pandemic.

Recognising strong interest from industry, AusIMM, together with co-hosts CSIRO and the IMPC Council, have advised that they will instead present a regional event, the IMPC Asia-Pacific 2022. This will be the second Regional Mineral Processing Conference organised under the auspices of the International Mineral Processing Council.

IMPC Asia-Pacific 2022 will bring together delegates from Australia, the Asia-Pacific and other regions to share best practice and knowledge in mineral processing in Melbourne, Australia, in August 2022. This smaller, regionally-focused event will precede full IMPC Congresses in Washington in 2024 and Cape Town in 2026, before the full-format IMPC Congress returns to Melbourne in 2028. Preparations for IMPC Asia-Pacific 2022 are underway, with further information regarding the format, content and event logistics to be shared over coming weeks.

November update: Covid rages in Europe; a worrying new variant and the effectiveness of masks

Coronavirus is still rampant.  The World Health Organisation is very worried about Covid-19 raging throughout Europe, with protests against new restrictions taking place in many countries as cases rise, and Austria is currently in full lockdown. 

Most of the earlier restrictions have been removed in the UK, but last week flights to many southern African countries were cancelled due to a worrying new heavily mutated strain, Omicron, reportedly originating in Gauteng, South Africa. Were the UK and other rich nations morally wrong in vaccinating as many of their populations as possible, rather than distributing the vaccines to the poorer countries of the world? "We are not safe until everyone is safe" has become a mantra, and maybe Covid will be back to bite us.

Wearing a mask is the most effective way in which the public can curb Coronavirus cases, a study has found. Global research has found that masks can slash incidences of infection by 53%. The first systematic review of its kind, published in the British Medical Journal, has found that non-pharmaceutical measures, such as mask-wearing, social distancing and handwashing, are all effective at keeping infection numbers down. Researchers at Monash University in Australia and the University of Edinburgh found that wearing masks was the most effective of the three and have called for their use alongside vaccines.

Prior to the last day of the month, when face coverings became a legal requirement again in shops and public transport, they were not mandatory in England, although they were in many countries in Europe. The UK Government guidelines had stated that "Face coverings are expected and recommended in indoor spaces where you come into contact with people you do not normally meet".  Not everyone abided by this guideline, but many did, in deference to other people.

So why did our embarassment of a Prime Minister not set an example? His main contribution to COP26 (posting of 15 November) was an excruciating speech to delegates imploring them to believe that the UK was not a corrupt country, but he perhaps gained the most media coverage by sitting next to the 95-year old Sir David Attenborough, while not wearing a mask.

An alert PM with Sir David Attenborough on his left

But worse than this, in the following week he appeared maskless on a hospital visit, where the advice to visitors is to keep visits to a minimum, and wear masks when entering the hospital. It's hard to be clearer than this, and any sensible person would agree that this not only applies to the act of entering the hospital, but also of being in the hospital. So why was Johnson not wearing a mask during his visit; all the doctors and nurses were wearing masks. It’s completely incomprehensible behaviour from this bumbling buffoon, surely the most egregious (word of the year apparently) prime minister in Britain's history, leading a government of inept weaselly sycophants.

Spineless government ministers, even the health secretary Sajid Javid, defended his hospital visit, saying that he followed the rules! Even if he had followed all the rules, which seems highly doubtful, why did he not go beyond the rules, setting an example, knowing full well that he would be photographed? Johnson said that he only took his mask off for about 30 seconds, but reports from the hospital suggest that he was asked 3 times to wear a mask.  More of his lies!

Spot the bare-faced liar in the Commons

According to a report early in the month in the i weekend newspaper, there are three Whitehall scenarios for when the public can forget about Covid-19. The paper says that an optimistic prediction will see the virus become routine in late 2022 or 2023, with the likeliest situation being that the world will escape the shadow of Covid in 2023-2024. The highly unlikely and most pessimistic forecast estimates mass infections until 2026, the paper adds. But this was all before the emergence of the Omicron variant.

In view of all this, we feel that MEI has probably made the right decision in making our next 3 conferences in 2022 online events, with the hope of running Process Mineralogy '22 as a hybrid at the end of the year.
