  • Extraction of Gold from Platinum Group Metal Ores

    Gold is typically associated with platinum group metal PGM ores and is ultimately recovered in the precious metals refineries. This chapter summarizes the extraction and refining of gold from PGMbearing concentrates and secondary materials.

    Aug 01, 2017· Metals like copper, mercury, silver and gold are less reactive. Metals at the bottom of the reactivity series can be obtained by heating their compounds. For example, when cinnabar HgS is heated in a furnace, it is reduced to metallic mercury. Metals in the middle of the series like zinc, iron, nickel, tin, lead, etc., are reduced by a chemical reducing agent like carbon or carbon monoxide.
