production of carbon gold ore
The Mining Process
This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution. We then "strip" the gold from the carbon by washing it with a caustic cyanide solution. The carbon is later recycled.

Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and .
Extracting Gold
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

The flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mines has low beneficiation costs. [Appliion]: Gold Flotation Process is used to process fine gold, sulfide goldcontaining quartz ore, multimetal goldcontaining sulfide ore, and carboncontaining ore.
Cyanide Use in Gold 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.
