  • Tailings What are tailings? Their nature and production

    What are tailings? The waste from the mining industry. . Tailings consist of ground rock and process effluents that are generated in a mine processing plant. . (below water deposition), high density thickened tailings or dry stacking can be implemented to control oxidation of sulphides and the mobilisation of metals.

  • Pressure Oxidation Overview Gold Ore Processing (Second Edition .

    May 13, 2016 . Oxidation releases encapsulated gold grains from the sulfides and makes the oxidation residue of the ore or concentrate more amenable for gold recovery by cyanidation in a subsequent leaching step. Pressure oxidation of gold ores is therefore a pretreatment leaching step to enhance gold recovery.
