In South Africa's Bushveld complex and a limited number of other ore bodies, platinum group metals occur in sufficient quantities so as to make it cost efficient to extract these metals. At Russia's Norilsk and Canada's Sudbury deposits, the metal and other PGMs are extracted as by-products of nickel and copper. Extracting platinum from its ore is both capital and labor intensive. It can take ...

As part of its strategic and critical minerals program, the U.S. Bureau of Mines investigated methods for beneficiating and recovering platinum-group metals (PGM) from ores found in the Stillwater Complex, the only primary resource of platinum-group metals located in the United States. Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development ...

13.04.2020· This process is necessary because platinum, even in ore, needs to be removed from other substances. Advertisement. Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it. It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the ...
