The third step is the extraction process. This is done by crushing the ore into minuscule pieces, once this is done the next process the platinum must proceed through is the flotation separation process, which relies on air particles to push the Platinum particles to the top. They are then skimmed off for refining.

Extracting platinum metals
The AARL process consists of three steps: a hot acid wash followed by a hot caustic cyanide pre-treatment and afterwards elution with hot deionized water at high pressures (up to 300 kPa). According to the researchers, test results show that effective elution of platinum- and palladium-cyanide with the AARL method is feasible. (Page 1) …
