Separating the Platinum Group Metals by Liquid–Liquid .

To extract the platinum group metals from the ore, and to refine them to the very high purity required for their many applications, requires a tude of complex operations. At present the final refining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals, but this is inefficient as far as the ...
