Outotec gold refining process Both atomized gold bullion and silver anode slime can be pre-leached to remove impurities of base metals. Next step of the refining process is an oxidative leaching step. Gold and platinum group metals (PGM) containing in a bullion/slime are leached in a solution of hydrochloric acid.
In this myth, fine gold particles were believed to be trapped within the skin of the fleece, thus alluding to the early practices of gold recovery from rivers. Since then, gold extraction and processing technologies have evolved. During the Roman Empire period, Emperor Augustus made significant advancements in hydraulic gold mining.
Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts …
