Bacterial leaching technology in sulfide ore battery of NSFC

摘要

Ore contains a kind of mineral or a group of minerals. It needs a temperature higher than 45 ℃ to effectively oxidize ore or each mineral. This process includes the adhesion of elemental sulfide in ore, and the intermediate bacteria existing in ore heap oxidizes elemental sulfide at a temperature below 45 ℃ to produce this thermal oxidation and sulfur sulfate. And gradually improve the internal temperature of the battery, so that thermoelectric bacteria can operate. Elemental sulfides are either mixed with ore during polymerization or with ore before or during battery formation,Provide 2% to 20% elemental sulfide (P / P) in ore
