I had the pleasure of attending the SAIMM Rare Earths 2nd International Conference 2024 in Swakopmund, Namibia on June 19-20.
The event began with the Welcome Cocktail & Early Registration on Tuesday 18th June, at the Swakopmund Hotel and Entertainment Centre, where the conference was held.
I spent a pleasant couple of hours chatting with old friends and new whilst enjoying a glass or two of wine and some food.

The next morning began with conference chairman Rasoul Hassanalizadeh welcoming us all to the event. Unfortunately, Rasoul could not make it to the conference in person, but it was no problem to link up with him remotely.
We then had a presentation from the current SAIMM President, William Joughin, giving us the history of the
SAIMM, as well as it's current objectives and a breakdown of it's membership.

Following on from William, we began Session 1: Exploration, geology, and mining of selected REE ore deposits. The Keynote Address was an online presentation by Okay Çimen, associate professor and a senior geologist at Munzur University, Turkey. Dr Çimen presented, "Rare earth element deposits and occurrences in Turkey: Opportunities and limitations for international investors".
This was followed by two more papers before the morning coffee break: "An assessment of rare earth elements in borehole cores from the Ermelo, Witbank and Waterberg Coalfields, South Africa: Focus on the mode of occurrence", presented by Duduzile Modiba from the University of the Witwatersrand and the University of Johannesburg, and "Rare earth market intelligence: Magnets defining the outlook" presented by Katlego Matlou of Project Blue.

Then we had 3 presentations before the afternoon coffee break. First up were two presentations from Olga Bazhko of Mintek and Johanna van Deventer of Purolite: "Application of ion exchange technology for the upgrading and purification of rare earth elements" and "Recovery of rare earth elements from low concentration acidic streams using ion exchange resins".

There was then an icebreaker quiz, which I confess I didn't attend as I needed to get back to my hotel and change into some warmer clothes, ready for the Conference Dinner at the
Tiger Reef Beach Bar and Grill.

The second day of the conference began with an address from Veston Malango, CEO of the Chamber of Mines in Namibia, who gave us an overview of the mining industry within the country at the present moment.

We then launched into Session4: Processing and refining/beneficiation with three more papers before we broke for lunch.
Sean Momberg of ProProcess Engineering began the session with "Strategic considerations in the construction of a rare earth facility in Angola: A comparative analysis of modular ex-works construction and traditional stick-build approaches", followed by Chiara Carrozza of Italmatch Chemicals with "Rare earth extraction with IONQUEST 801 initial modelling development", and Tebogo Mokgomola of Mintek presenting "Development of a physical separation preconcentration process for the extraction of rare earth bearing ore".

After lunch, we had two more presentations before the conference finished. The scheduled paper from the University of Cape Town was not able to take place, and instead Sanjey Bhoowanpursadh of DMT Group presented "Financial challenges in the African critical minerals revolution".
The conference closed with another paper from Mintek, presented by Buhle Xakalashe and entitled "Rare earth elements research conducted at Mintek".
I would like to thank the organisers of this event, the
SAIMM, for allowing me to attend and for a very enjoyable couple of days. A special mention must also be made to Selo Ndlovu from the University of the Witwatersrand who stepped in at the last minute to perform the duties of the Conference Chair.
MEI are organising
Critical Minerals '24 in Cape Town from November 14-15, 2024 and I hope to see you there!
