The gold mining industry is presented as an overview covering key aspects and examples regarding gold discovery, deposits, and production. Segmentation of gold ore types is made based on major processing routes, ie., freemilling, refractory, heapleachable, and concentrate sales.
Copper Mining and Processing: Processing of Copper Ores. Copper processing is a complied process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called hodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo
and seven carboninleach tanks. The effect of processing the oxide and sulphide ores studied was examined and the model shown to satisfactorily describe the extraction of gold from the Telfer oxide ore. A sensitivity analysis of the effect of process changes on this ore was then undertaken, where the correct operating response to pregrobbing

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
Lead and zinc ores are usually found together with gold and silver. A leadzinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue. Forms of Lead and Zinc Ore
A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to 200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns
