  • Cyanide Leaching Chemistry Gold Cyanidation

    The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH

    The reaction, known as Elsner's Equation, is: 4 Au + 8 CN + O 2 + 2 H 2 O = 4 Au(CN) 2 + 4 OH Although the affinity of cyanide for gold is such that it is extracted preferentially, cyanide will also form complexes with other metals from the ore, including copper, iron and zinc.

    The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward. In a typical application, a slurry of the ground ore is mixed with cyanide in the presence of activated carbon.

  • Cyanide Leaching Of Gold mineengineer

    Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
