Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation concentrate should be considered. Producing a pyrite concentrate with associated gold maximizes gold recovery.

Gold extraction

Gold extraction

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.

Rock Crushing methods and How to recover gold from Ores

Gold is often found associated with the mineral quartz. It is sometimes associated with other minerals as well, including iron and manganese oxides, calcite, pyrite and other sulfides as well. It is not uncommon for prospectors, especially those who operate metal detectors, to find a rich gold bearing specimens of ore. Sometimes the best use of these minerals is to sell them at specimens.

Copper Mining and Processing Processing of Copper Ores

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides
