The process of beneficiation of minerals in South Africa and the dialogue around it has been taking place for years, yet, platinum beneficiation has been at a snail pace. This is despite South Africa producing approximately 80% of the world's platinum and being in possession of the world's largest known deposits of platinum group metals (PGM).
understanding of the behavior of the liberation process and beneficiation responses of the platinum group metal (PGM) minerals is not new. Fine milling of the tailings or the concentrate to increase recovery and/or grade has been successfully implemented at a number of platinum plants1.
The beneficiation process for platinum group metal (PGM) ores involves a sequence of grinding, gravity separation, and flotation treatments. Achieving the best possible recovery hinges on attaining the desired level of liberation of PGM minerals. Consequently, the choice of the grinding process and its specific stages is informed by …
The most common and notable example of this are precious metal values (gold, silver etc.) where the beneficiation process is applied directly on run-of-mine ores followed by the extraction of gold and in some cases silver as a relatively pure metal within the mineral processing circuit. 2.0 Processing Approach and Method In broader terms, ...
