Sample preparation aqua regia with, occasionally, the addition of hydrofluoric acid is the most used lixiviant, and is applicable to most ore types.Other combinations of acids as well as cyanides are also used, and pre-roasting is sometimes applied.Digestion time and amount of reagent vary, quite naturally, with the amount of acid consuming materials in the sample.Thus, raw ores are.
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.Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills.
