Advantages of sodium cyanide gold mining

sodium cyanide sodium cyanide is an inorganic compound with the formula na c n.it is a white, watersoluble solid. cyanide has a high affinity for metals, which leads to the high toxicity of this salt. its main application, in gold mining, also exploits its high reactivity toward metals.it is a moderately strong base.when treated with acid, it forms the toxic gas hydrogen cyanide

history cyancoin 1988, cyanco (under the ownership of mining services international msi) undertook to build a liquid sodium cyanide plant in winnemucca, nevada, in the heart of gold mining country. until this time, producers of sodium cyanide made a liquid product nearer to the raw materials, which was usually thousands of miles from where the mines were.

gold mining using sodium cyanide asiamercury liquid of these methods, cyanide leaching process or cyanidation, is one main method that is highly and most often used for doing this procedure. as the name implies, the main component of this process is the sodium cyanide solution. here we will give the general overview on how this ageold gold mining

why does gold react with cyanide and sodium hydroxidewhy does gold react with cyanide and sodium hydroxide and what is the chemical reaction's impact on gold's atomic structure and bonding? what i think is since in the 'flotation' process, when the water, chemicals and other substances are added, gold isn't affected and neither is the pyrite, but when the cyanide and caustic acid is mixed with the slurry, it separated both substances, then the
