  • Effect of Potassium Cyanide on Gold & Metals

    Metallurgists found that gold leaf would not dissolve in a solution of potassium cyanide from which the air had been expelled by the passage of a current of hydrogen, and that the addition, under these circumstance, of either potassium dichromate, chromate, chlorate, perchlorate, nitrate, or nitrite or of ferric hydrate or bleaching powder,Potassium Cyanide Potassium cyanide is Best Chemistry Potassium Cyanide Potassium cyanide is a compound with the formula KCN This colorless crystalline salt, similar in appearance to sugar, is highly soluble in water Most KCN is used in gold mining, organic synthesis, and electroplating Smaller applications include jewelry Get Pricepotassium cyanide used in gold miningCyanide's efficiency makes mining more wasteful Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold Partially due to cyanide, modern mines areCyanide Use in Gold Mining Earthworks

  • Should cyanide still be used in modernday mining?

    Cyanide still has an important role in gold mining and when used will always be a risk Though Mudd believes: “Cyanide can be managedHowever, it does require a lot of due diligence and careful attention” “Using best practices and auditing is the best thing and mining companies are doing that,” agrees BlackmoreThe Cyanide Code The “International Cyanide Management Code For the Manufacture, Transport, and Use of Cyanide In the Production of Gold” (Cyanide Code) is a voluntary, performance driven, certification program of best practices for the management of cyanide in gold and silver mining Participation is open to gold and silver mining companies, manufacturers of cyanide, and transporters ofThe Cyanide CodeThe process involves the use of Potassium Cyanide, Hydrogen Peroxide (35%) and warm water When Gold is processed in this solution a small explosion occurs releasing a cloud of toxic gas and a quantity of toxic water as well The gold is stripped and made brighter in appearance (1% gold is lost in the process to the water solution)GOLD "BOMBING" PROCEDURES AND REGULATIONS
