mining gold cyanide formula

  • Gold cyanidation

    Gold cyanidation is a hydrometallurgical technique for extracting gold from low grade ore by The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to pyritic ore. The chemical reaction for the dissolution of gold, the "Elsner Equation", follows:.
