To achieve optimum gold recovery from the certain sulfide ore body, the ore must be finely ground to achieve proper oxidation and mineral separation. The ore is separated into stockpiles after it has been mined. These stockpiles are based on gold content, sulfide content, and carbonate content. The ore is blended prior to being fed into the crushing circuit. The ore passes through crushing and

In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense. This is also true for operators processing large quantities of hard rock material.

Mercury Free Gold Processing. By Kevin Telmer
Stamp mills used mercury to extract gold from the crushed rock, increasing the yield. Crushed gold ore was combined with liquid mercury. The gold stuck to the mercury and this slurry was then boiled, evaporating the mercury, leaving behind the gold. Some mercury boiled off into the air, and some was recaptured and used again. About 10-25% of all mercury used was lost in tailings.

Depending on the mineralogy, gold and other metals are extracted by physical processes such as crushing, milling and gravity separation. When this is not achievable or economically viable, gold is usually separated from the ore by chemical dissolution in cyanide. This process is referred to as leaching or cyanidation which occurs in conjunction with physical processing.

In over 80 developing countries in the world, mercury is the artisanal gold miner’s go-to for separating gold from concentrated ore. Due to a lack of resources and available alternatives, mercury is often handled with bare hands, and in the effort to amalgamate gold, much of it escapes into waterways and soil where it enters the food chain. Most dangerously, the amalgamate is burned, and
