Thecyanidation gold extraction processincludescyanide leaching, washing and leaching of the leaching slurry, extraction ofgoldfrom thecyanideorcyanide slurry, and smelting of the finished product. Cyanide Gold Extraction MethodsGet a Quote
Thegoldcyanidationprocessis the most important method ever developed for extractinggoldfrom its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery ofgoldthan plate amalgamation and is easier to operate than the chlorine or bromineprocess.Get Price

By far, potassiumgold cyanideis the most common source. 37 Because thegoldsolution normally containscyanidecompounds, extra precaution is needed in theprocessand waste treatment of the plating solutions. 12,19 The reducing agents used are also as diverse as thegoldsource, such as sodium hypophosphite, dimethylamine borane, sodium ...Get Price
GREENGOLDTECHNOLOGY can provide a significant opportunity to reduce operating costs and at the same time improve environmental performance. The resin basedprocessoffers a proven method for achieving virtually complete removal and efficient recovery ofcyanide, dissolved base metals and precious metals fromgoldplantprocessstreams.Get Price
Under the 400 mesh condition, thegoldleaching rate increased by 8%. If the tower grinding machine is used to implement the edge grinding and immersionprocessingoldmines, it will be a major innovation in thecyanide goldextractionprocess. Thecyanide goldextractionprocessalso suits for copper leaching, zinc leaching, sliver leaching, etc.Get Price
Theprocessof extractinggoldfrom ore is a multistep one, and historically it has involved the use of some dangerous chemicals, includingcyanideand mercury. Cutting-edge extraction techniques have eliminated the need for these chemicals and made theprocessmuch safer. It's still too dangerous to try at home, though.Get Price
Goldshould be separated from other minerals present in the ore. Asgoldis insoluble, it should be separated from other minerals to make it soluble. Hence, sodiumcyanidecan be added, wherecyanideions form a complex ion with the molecules ofgold. Thecyanide processis as explained below-The ore is grounded and crushed.Get Price
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.Get Price

The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
