1983-1-1  Thus, DPBTP can extract selectively metals such as silver, gold, platinum and palladium. It seems that the sulfur atom of the ligand is responsible for these extractions, behaving similarly to the sulfur atom in dioctylsulfide and other sulfides, which has the properties of a soft base [4, 8].

Extraction of gold from platinum group metal (PGM)

2005-1-1  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.
