The conventional cyanidation gold extraction process is divided into two types according to the treatment materials: one is a cyanide plant that processes flotation gold concentrate or treats amalgam and re selects tailings. The other is to treat muddy oxidized ore, using a full mud mixing cyanide gold extraction process plant.
Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
Oct 20, 2014· Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no
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.
