Platinum, along with the rest of the platinum-group metals, is obtained commercially as a by-product from nickel and copper mining and processing. During electro refining of copper, noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as “anode mud”, which forms the starting point for the extraction of the platinum-group metals.

Extraction of Gold from Platinum Group Metal Ores

01-01-2016· Alloys containing gold, silver, PGMs, and other metals are usually first processed using the Miller process to remove base metals and cast into anodes. Gold–PGM alloys are processed using the Wohlwill electrolytic refining process, also known as the gold cell. The Wohlwill cell uses impure gold alloy as anodes and deposits pure gold at the cathode.
