Bio-ox Tank (Biological Oxidation Tank) mining equipment
Type:Leaching Tank | Place of Origin:Jilin China (Mainland) | Brand Name:Chang Tan | Model Number:SWYC |
Material:Stainless steel | mean:bio-oxidation | Condition:New |
This equipment used for the bio-oxidation of refractory leachable gold concentrate containing arsenium --thiourea RIP gold extraction processing method
Its features are biological oxidization., i.e.; after gold concentrate remove iron scrape by regrinding and magnetic separation, remove agents by thickening, adding water,sulfuric acid and biological medium according to the proportion to mix slurry of solid concentration 16%-25% with biological oxidation tank, then entering the to the biological oxidation tank for biological oxidation pretreatment,
Inoculated oxidized sulphurous acid bacillus and other autotrophs in biological oxidation tank to oxidize the sulphide materials of pyrite and arsenopyrite.
The oxidation process takes 4-6 days,
Oxidized slurry to process solid- liquid separation by removing of iron scrap,graphite carbon and thickening,washings and filtering .
The separated liquid after treatment return to the concentrate mixing cycling operations
The separated solid oxide slag adding into the next step for gold extraction
