· Beneficiation and recovery of platinum group metals (PGMs) from the major reefs involves a complex set of unit operations that has evolved greatly over the last few decades. Over time, a number of interesting flowsheets have been developed for the concentration, separation, and purification of PGMs. Gold from this source is estimated to be some 5 t/year and is considered to be a bymetal with ...
