Chlorine was first used in recovery of gold from its ores in 1851 by Karl Friedrich Plattner, who used metallic iron to cement gold from the chloride leach solution (Aaron, 1881) The barrel chlorination process used chlorine gas generated with bleaching powder and sulfuric acid inside a rotating barrel
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
24/04/2017 · Allow four hours for the gold to dissolve, stirring every 20 minutes The chlorine reacts with the gold inside the ore to form gold chloride Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments Collect the filtered gold chloride solution in a flask
18/01/2017 · The first step in gold smelting involves processing the gold ore The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together The gold ore is then pulverized using pressure to create very fine particles This is a chlorination process that refines gold to a
The objective of this research was, on one hand, to study gold extraction from an alluvial material, through a pyrometallurgical process, using chlorine gas as a reactant, and, on the other hand, to characterize the initial material and chlorination residues, using X-ray fluorescence (XRF), X-ray diffraction (XRD) and scanning electronic microscopy (SEM) techniques
