    Sodium Cyanide Gold Mining Extraction Plant Use in Mining International Cyanide Management Code Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and stone forms, including solid briquettes, flake cyanide and liquid cyanide Sodium cyanide is supplied as either briquettes or liquid, while calcium cyanide is supplied in ContactHow is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore There are two types of leaching: 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 metalimpregnated solution which is stripped of gold and resprayed on the heap until the oreCyanide Use in Gold Mining EarthworksHighly toxic sodium cyanide (NaCN) is used increasingly by the international mining community to extract gold and other precious metals through milling of high grade ores and heap leaching of low(PDF) Detoxification of Cyanide in a Gold Processing Plant
