Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.

gypsum using the sulphur – either as an industrial product or a benign tailing” Taking such a route with high sulphur ores allows companies to remove the sulphur completely before gold extraction takes place leading to “nonacid leaching tailings” Howlett saidGet Price
Gold CIL CIP Gold Leaching Process Explained CCD CIL stands for carboninleach This is a gold extraction process called cyanidation where carbon is added to the leach tanks or reaction vessel so that leaching and adsorption take place in the same tanks CIL is slightly different from another gold extraction process called CIP or carboninGet Price
