Process to Recover Gold from Sulfide Ores GOLD ...

27/05/2016· In fact, we have tons of sands coming from the gold extraction process using cyanide. These sands still have in average 20gr/ton of gold. The problem is that we haven't found a reliable process or technology to effiently recover the gold because these sands contain elements making cyanide based treatment useless.

How phosphate is mined and processed

Processing The phosphate is sent to a chemical processing plant, or fertilizer manufacturing plant. Here, molten sulfur, shipped to Florida ports and trucked to the plant, is used to create sulfuric acid. The sulfuric acid is then mixed with the phosphate to make phosphoric acid.

A fundamental study of the alkaline sulfide leaching of gold

could be selectively recovered using cheap solid materials for adsorption of the gold . Finally the alkaline sulfide solutions which are barren of gold can be recycled for further gold leaching or further processed with low temperature oxidation to sodium sulfate, Na 2SO 4. This has been practiced in industry.

Biooxidation of sulfidic refractory gold ores ...

The typical gold recovery of the process is 90 95%, whereas it works at a variety scales from 30 1000t concentrate/day. The process is modular making a later expansion of the plant possible. It is also considered able to treat a variety of ore types through the lifetime of a project, from transition ores to fully refractory ores.

Gold Precipitation Methods Mineral Processing Metallurgy

27/07/2016· Gold was not precipitated at all, nor was copper, if the solution contains 0.15 per cent or more free cyanide. As with aluminum, gold precipitation by sodium sulphide regenerates all the cyanide combined with the silver in the pregnant solution. The reactions involved are shown in the equation: 2NaAg2 + Na2S = Ag2S + 4NaCN

Gold Ore Processing

Flotation is widely used in gold processing. In China, 80% rock gold is processed by flotation. Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost.

Recovery of gold from sulfide refractory gold ore ...

01/04/2021· The major chemical components of the sulfide refractory gold ore and pyrite are shown in Table 2. The sulfide refractory gold ore contains 30.34% Fe, 22.23% S, 11.19% As, 3.24% Al and 60.25 g/t Au. The total content of Fe, As and S is up to 63% of the sulfide refractory gold ore. The pyrite contains 43.36% Fe and 41.26% S.
