Gold bulls were disappointed that the price did not break through the $2,000/oz ceiling; nevertheless the current stable price run has helped to maintain a strong interest in gold projects. Gold processing has a couple of unique features. The first is the sheer variety of the mineralogical characteristics and associations, which is what this

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher

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.
