Gold Cyanide Method Technology Industry Of Gold MiningWhat is Gold Ore worth High Grade Mining Ore

Gold cyanide method is the process of dissolution of gold ore using cyanide chemicals because every atom of gold requires dissolution of the mineral carrier or impurity with the stoichiometry of two cyanide soluble compoundsAlso consider that gold concentrations in ore is never consistent often occurring in pockets rather than consistently throughout So a mine that produces some high grade ore will also process tons of ore with almost no value To the naked eye these ores may look exactly the same
