the principal economic value of the ore is in the silver; the gold appears as metallic "free" gold. Inspection of size fractions indicate sulphides liberate from the gangue at 65 mesh; however, a very find grind, probably 600 mesh, would be required to separate intergown sulphide minerals.
Feb 24, 2013· was351, Depending on gold to silver ratio content of the metal, the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold, and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the gold.
Impure gold, as it commonly occurs in deposits, has a density of 16 to 18, whereas the associated waste rock (gangue) has a density of about The difference in density enables gold to be concentrated by gravity and permits the separation of gold from clay, silt, sand, and gravel by various agitating and
Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means.

Removing the goldbearing rock from the ground is just the first step. 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.
Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in ( M) HBr, potassium peroxodisulfate and acetone:water:nitric acid media. The exchangeable anion Cl − of the ion exchanger Dowex 1X 4 is replaced by Br − using (6 M) HBr solution.
Leaching of gold ore (Konzentrat) is stirred in a separate cyanide solution under intensive aeration and oxygen content in the solution 59 mg/L. An example implementation of the proposed method are the results of the following experiments. Flotation concentrate Berezovsky mine (Ural) size contained mm 38 g/t gold.
