In the case of Goldstrike, this was a doublerefractory ore combining sulphideoccluded gold with pregrobbing carbonaceous material that rendered the ore unsuitable for conventional cyanide leaching and carbon adsorption In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc, to achieve either one or two purposes Gold Metallurgy and Leaching ProcessMostly, the gold obtained through gold electrolysis is usually very pure, almost 99999% In fact, this procedure is the best method for processing gold with the highest karatage (24 Karats = 100 percent gold) This is why gold electrolysis is very common in countries where pure gold pieces are given priority over the ones with low karatageHow to Refine Gold: 2 Major Techniques of Gold Refining

The environmental impact of gold production
processing As nonrefractory ores become depleted, the ability to recover gold from refractory ores has become more important For an ore grade (ie metal content) of 35 gram per tonne of ore, the study estimated that production of each tonne of gold from nonrefractory ore used approximately 200,000
