Extraction of Gold

Gold Amalgamation-process With pyritic ores a preliminary roasting to eliminate sulphur is necessary. The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled.
