Processes Of Raw Gold Ore To Final Stage

Processing of metals in the solid state can be divided into two major stages: first, the raw material in the form of large ingots or billets is hot-worked, usually by rolling, forging, or extrusion, into smaller shapes and sizes; second, these shapes are processed into final parts and products by one or more smaller scale hot or cold forming processes.

29-02-2016· 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.

In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue. Assaying

18-01-2017· Once the raw ore has been processed the next step of the gold smelting process involves the use of chemicals to remove impurities from gold. At this stage, most of the impurities in the gold material are traces of other metal elements. Gold can easily be purified at this stage by using chemicals such as potassium cyanide or mercury.
