Bio-oxidation Plants of Refractory Gold Concentrate in China

摘要：

The paper introduced bio-oxidation plants of refractory gold concentrate in China and CCGRI cultures.CCGRI cultures are composed of bacteria and archaea. Archaea Ferroplasma acidiphilum is very thick and fills whole mineral surface. It plays a more dominant role in CCGRI process.Several years of practice has proved that the operating temperature in bioreactors between 38～52℃,gold recovery is almost same. Pulp concentration has been increased each year and reached to 25%.
