Alban Lynch is 90 years old on Saturday

On behalf of MEI and all of us in the mineral processing community, I would like to wish Prof. Alban Lynch a very happy 90th birthday, which he will be celebrating with family on Saturday.

Alban was one of the great 20th century mineral processors, particularly in the field of comminution and his name probably appears more than any other throughout the MEI Blog. The first Director of Australia's JKMRC, he was one of the first persons that I interviewed for MEI, six years ago (MEI Blog 11 August 2014) and then a year later he reciprocated by interviewing me (MEI Blog 2 November 2015).

I last saw Alban 10 years ago at the 2010 IMPC in Brisbane, where he and his co-authors Mike Nelson and Greg Harbort signed copies of the newly launched book History of Flotation.

The most recent photo of Alban on the blog was with one of his most famous students Prof. T.C. Rao (MEI Blog 5th November 2016) his co-worker in the late 1960s on the pioneering development of mathematical models of mineral processing systems.

Alban is living in a nursing home in suburban Brisbane, and has been in lockdown. Fortunately the lockdown lifted earlier in the week so a few family members will be able to take him for lunch on Saturday and then celebrate via videolink with the rest of the family in the afternoon with cake and speeches. If you would like to leave birthday wishes, his daughter Suzy Lynch-Watson will show Alban the blog and any comments during his birthday celebration.

Peggy Fuerstenau, 1932-2020

It is with great sadness that I report that Doug Fuerstenau’s gracious wife, Peggy (Margaret Pellett) died on May 30th from coronary-pulmonary complications. I had the pleasure of meeting Peggy for the first time last year in Denver, where Prof. Fuerstenau (MEI Blog 20 July 2015) was presented with the IMPC's Distinguished Service Award at the SME Annual Meeting. Doug was also the first recipient, in 1995, of the IMPC's Lifetime Achievement Award.
Peggy was born in Franklin, New Jersey, on May 7, 1932. She met Doug while she was an undergraduate student at Radcliffe College (Harvard) and Doug was a doctoral student at MIT working under Professor A.M. Gaudin. After their marriage in 1953, Peggy completed her studies in American history and Doug began his career as an assistant professor of mineral engineering at MIT.  After graduating from Radcliffe, she continued her education at Simmons College in Boston, where she received an M.S. degree in library science.   Later she was the caring mother of their son and two daughters. Her main outside activities involved volunteer work, serving as a docent at the Oakland Museum and on various programs related to University student welfare and persons in need.

During Doug’s long career at the University of California, Peggy was a welcoming hostess for dinners and receptions in their home to many dozens, if not hundreds, of professional colleagues and visitors to Berkeley from all parts of the world.  Doug’s many graduate students and postdoctoral researchers fondly remember her many buffet dinners for the group and their spouses. 
Other international persons in the mineral world came to know her at International Mineral Processing Congresses. She set a record that probably will never be surpassed in that she was an accompanying person at thirteen IMPCs, the first in 1970 in Prague and the last in 2014 in Santiago.  For the San Francisco IMPC, she was a member of the organizing committee and led planning for the program for accompanying persons. Prof. Fathi Habashi has kindly supplied this photo:

In addition, Peggy accompanied Doug to many SME/AIME Annual Meetings, toured a few flotation plants with him, and also went on a few Homestake Mining Company trips.  In 1990 the two had a special underground tour of the Homestake Gold Mine in South Dakota, and the photo below shows Peggy and Doug at 2200 meters below ground on the  7200 Level where the rock temperature is 57 degrees Celsius. The deep mine refrigeration thankfully maintained a very satisfactory ambient temperature.
Although Peggy's education was in liberal arts, she had some familiarity with mining.  Her oldest uncle’s entire career, starting in 1907, was with the New Jersey Zinc Company in Franklin, advancing to mill superintendent at this complex gravity and magnetic separation operation.  He told Doug about Professor Richards coming there as a consultant from MIT. In his Handbook, Taggart describes the Pellett Classifier used in the Franklin mill where three different minerals, franklinite, willemite and zincite in calcite, were recovered from a rich ore containing 20% zinc. To mineralogists, the dumps at Franklin are world famous in that over 350 different minerals occur in the region, 90 of which are fluorescent, and two dozen of those occur nowhere else in the world.
Very significant to Peggy and Doug's family life was the Pinecrest cabin in the High Sierra that they purchased in 1965. Being located at an elevation of 1700 meters on the west slope of the Sierra leads to year-round relaxation and recreation and in the summer, Peggy fished and swam in the Pinecrest Lake, and in the winter there were various snow activities.  After their children became avid downhill skiers, Peggy and Doug switched to cross-country skiing.  Depending on schedules, several overseas visitors enjoyed Peggy’s hospitality at Pinecrest. Every fall, Doug had a weekend there with his graduate students but Peggy stayed completely away that weekend. The photo shows the beauty of the area after a fresh snow.
Although she was not a musician, Peggy had a great love for opera.  She and Doug had season tickets for the San Francisco Opera for fifty years and estimate that they attended nearly 300 opera performances, including some at other opera houses during their travels.  They also found time to attend a few symphony concerts and plays each year in the San Francisco Bay Area.  
In recent years, Peggy arranged for several different Road Scholar excursions in Europe and the U.S.  Their last trip to Europe was a non-technical Road Scholar excursion in November 2016 to Venice followed by a few days in Munich.  The photo shows Peggy enjoying the Grand Canal in Venice.
Doug tells me that during her last days, Peggy said several times that she was completely satisfied with the life that she had.

July: The Great Leap Forward

July 4th was the date that the hospitality business had been waiting for. Just as on the 4th of July Americans celebrate freedom from the British Government, on this day English citizens celebrated a similar release, as lockdown rules were further eased, apart from in the city of Leicester, where a resurgence in cases to 140 per 100,000 led to a tightening of the lockdown.
Cornwall in early July had one of the country's lowest number of Coronavirus cases, just 0.7 in 100,000, and Falmouth was soon buzzing with an influx of visitors,  restaurants and pubs doing a roaring trade,  and it was particularly good to see the old Chain Locker in action again.
Last week we had our first visitors of the year from outside Cornwall, Prof. Richard Williams, his wife Jane and son Tim, who were on a short break from their home in Edinburgh, where Richard is Principal and Vice-Chancellor of Heriot-Watt University. Richard was the subject of one of my MEI Interviews (MEI Blog 17 August 2015), when he was then a Pro Vice Chancellor at the University of Birmingham UK.
Social distancing has gone by the board in many cases, and while walking through the busy Falmouth main street, I said "don't mind me!" to a guy who passed inches away from me, and who replied that he had come down here to get away from all that crap!
A busy Falmouth town
And on that subject, there have been many reports of masses of waste, including human waste, being left on Cornwall's beaches, and on Perranporth beach a 14 year old boy who asked a family to take their litter away was hit over the head with a whisky bottle, and needed 11 stitches to the wound. Unbelievable behaviour!
Swanpool beach, Falmouth, July 30th
At the end of the month infection rates in Cornwall had risen to 4 in 100,000, only just below that of 5 for England as a whole, and tightened restrictions were imposed in the north of England due to a resurgence in cases. Let's hope that the great leap forward was not a leap too soon.

Sad news of the death of popular mineral processor Dan Alexander

We had some extremely sad news this morning of the sudden passing on Wednesday of Dr. Dan Alexander, a very popular figure who will be well known to many in our profession. He was only 48 years old.
Dan was Head of Technology Development at Anglo American, UK. Prior to that he was with the JKTech in Australia for over 14 years, from 2000-2015, where he was initially Operations Manager, and latterly CEO for 5 years.
He was a good friend of all of us at MEI, and a regular at MEI Conferences, particularly flotation, where he attended all but one of the conferences in the series. 
Dan (2nd left) at Flotation '09, with other well known mineral processors who had attended all MEI's flotation series:
Graeme Jameson, Jim Finch, Antonio Peres, Stephen Neethling and Dee Bradshaw
Last year he was also in Falmouth, for Physical Separation '19, and in the photo below he is with his close friend Dr. Ben Adair, CEO and Managing Director of CRC Ore, Australia, and a former Director of the JKMRC.

Ben writes "Dan often spoke fondly and thought very highly of MEI and the conferences you run. We loved being at the The Falmouth conference last year - it was a real highlight for both of us.
Dan was not only a very gifted mineral processor in his own right, but he also had an outstanding vision of the future directions needed for step change in energy, water, and productivity in the industry. 
He was the author and main advocate for Anglo American’s Concentrating the Mine innovation initiatives. No one agitated more for change and a more sustainable future for mining going forward. He was also, of course deeply committed to his wife Suzi and their young son James. A true family man in every sense of the word.
I lost one of my closest friends yesterday, but I also know his loss will be keenly felt by so many of our colleagues. He was also a true friend of MEI. Thank you for thinking of him and any tributes you give him will be deeply appreciated by all his friends".
We will deeply miss Dan, not only for stimulating discussion on mineral processing, but for his views on subjects outside our industry, particularly cricket, which he played at a high level in Australia. 
Our thoughts are very much with his family at this difficult time.

Pendeen Lighthouse to Levant Mine

The glorious stretch of coast path in Cornwall's Penwith Peninsula (or the Land's End Peninsula) is not only an area of outstanding natural beauty, but is also of great interest because of its important tin and copper mining history and legacy.
The small village of Pendeen has three excellent pubs, an indication of this once being a thriving mining community, serving the mines in the St. Just District. There is an excellent 4-mile circular walk from the village to the Pendeen Watch Lighthouse, and then along the coast path to the famous Levant Mine, which closed in 1930, eleven years after the tragic man-engine disaster (MEI Blog 20th October 2019).


Pendeen Lighthouse, also known as Pendeen Watch is an active aid to navigation, and was commissioned in 1900. This whole stretch of coastline, with its jagged rocks lying just below the surface of the water, has caused many a problem to passing vessels, one notorious area being that around Gurnard's Head, a headland a few miles further towards St Ives.
The walk along the coastal path from the lighthouse to Levant Mine is only 1.6 miles but allow around 45 minutes as there are a few ups and downs along the way, but nothing severe, the elevation gain being only around 280 ft.

From Levant, you can walk back to Pendeen along the road, but I would suggest that if time permits you continue along the coastal path for just under a mile to the iconic ruins of the Botallack Mine and the region of Cornwall's submarine mines (MEI Blog 20 October 2014). There is probably a no better historical mining walk anywhere in the world.
