Jameson Cell at Mogalakwena North: design and cost lessons for concentrator engineers
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
Glencore Technology’s Jameson Cell is delivering higher mass pull and improved concentrator recoveries at Valterra Platinum’s Mogalakwena North Concentrator in South Africa after four units replaced 40 conventional flotation cells. The compact Jameson Cells provide intensified mixing and aeration in a much smaller footprint, cutting the number of banks and associated piping, instrumentation, and maintenance points. For plant designers and metallurgists, the case signals scope to debottleneck existing flotation circuits and reduce capex/opex by substituting high-intensity cells for large fleets of conventional machines.
Technical Brief
- Four Jameson Cells were commissioned at Valterra Platinum’s Mogalakwena North Concentrator in South Africa.
- Commissioning outcomes include measurable increases in mass pull beyond initial performance objectives.
- Higher overall concentrator recoveries are being reported following the Jameson Cell installation.
- Performance gains are described as “continuing”, indicating stability rather than short-term commissioning uplift.
Our Take
In our database, Glencore Technology’s Jameson Cell is now being promoted across very different ore types – from South32’s Hermosa critical minerals project in Arizona to this platinum application in South Africa – signalling a push to standardise a compact, high-intensity flotation platform across multiple commodities.
The replacement of 40 conventional cells with four Jameson Cells at Mogalakwena North Concentrator aligns with Glencore Technology’s recent messaging that simplified, small-footprint circuits are better suited to AI-driven advanced process control, as highlighted in its separate APC-focused Jameson Cell coverage.
