Mining and Extraction: Oxide Ores processes for

The process used to treat sulfide copper ores begins at the mine site, where the copper bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Sulfate reducing bacteria BioMineWiki

Sulfate reducing bacteria SRB form one group of sulfate reducing prokaryotes.Main genus is Desulfovibrio. Desulfovibrio desulfuricans is often used to immobilize dissolved heavy metals as metallic sulfides.. Beijerinck showed in 1895 that living matter could reduce sulphate to sulphide in sediments under anaerobic conditions. Although many bacteria can produce sulphide, only a few do so at a

Recovery of Gold in Pyritic Sulfide Ores Mine

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35 recovery, and the best I have heard of is around 50 recovery.

OverviewRefractory gold processesHistoryTypes of oreConcentrationLeachingGold smeltingGold refining and parting

A refractory gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach s

Oxidative Hydrometallurgy of Sulphide Minerals

The oxidation of sulfide ores by ozone can occur by dissolution of sulfide species and the formation sulfate ion, as suggested by Elorza et al. Then, the global reaction of the pyrite oxidation in the presence of ozone can be described as follows: FeS2 + 2/3O 3 + 5/2O 2 + H 2O = Fe 2+ + 2SO 42 + 2H + 14
