Mar 07, 2016 0183 32 After several high-profile leaks and spills, the use of cyanide in mining operations is facing increasing public opposition with some countries banning it completely The toxic chemical is still widely used for the processing of certain ores, most notably gold, but should cyanide be phased out of ....
Cyanide Leaching Of Gold , and cause a increased use of cyanide, the copper-cyanide complexes formed by the dissolution will tend to inhibit the dissolution of gold in the cyanide solution Zinc, the element used to precipitate gold from solution, if present in the ore, will bond with the cyanide to form a zinc cyanide compound ....
The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation This process is more frequently referred to as leaching As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore...
