Gold Extraction & Recovery Processes

Feb 29, 2016 · The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching.

what geologic processes helped to form gold ore, oil and ...

Answer 1: Gold is concentrated in certain geothermal solution formed when magma is injected into water bearing rocks. Then, because of its large density gold gets transported by streams and concentrated into what are called placer deposits. These are fluvial sediments that occur along the banks of streams and rivers. What is gold ore? Ores.

Extraction of Gold

The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing. The crushing is effected by stone-crushers, rolling-mills, and stamp-mills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles."

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

In some cases, gold cannot be removed by cyanidation alone. Pyrometallurgy can also be used for gold extraction as well. This can include smelting, in which, the ore is reduced to a molten state as well as drying and roasting, in which other materials in the rock are oxidized to prevent them from hindering the extraction process.
