ore processing for leaching plants

Gold cyanidation - Wikipedia

Gold cyanidation is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex It is the most commonly used leaching process for gold extraction processes edit The cyanide that remain in tails streams from gold plants is potentially hazardous
