Outotec Gold Refining Plant

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.


The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, with fluxes of silica, feldspar, and borax, to remove impurities. Complete separation occurs within 1.5 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled. The anodes are approximately 99%
