  Gold Ore

  Lean-grade refractory sulfidic gold ores containing 1? g/ton of gold, which cannot be economically processed through conventional processes (e.g., Heap bioleaching of Carlin ores). 2. Refractory sulfide concentrates, where finely disseminated gold particles are locked up, making them uneconomical for direct cyanidation (e.g., Bioreactors: Biox-Outotec, BacTech, BIONORD).

  Gold Extraction & Recovery Processes

  Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process. For example, orebodies containing clays have problems due to the excessive amount of fine material liberated during the comminution process due to rheological and physiochemical properties are modified.
