Био-бык танк (биологическое окисление бака) добыча фас

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 Main technical parameters ItemUnitModel45505560657070758085909595100105110120125150160Diameter of tankmmΦ4500Φ5500Φ6500Φ7000Φ8000Φ9000Φ9500Φ 10500Φ12000Φ15000Height of tankmm50006000700075008500950010000110001500016000Effective capacitym374.75135.42215269402480572673785Impeller speedr/min33.530.64232117 2017 2010 1710 1710 1710 17Slurry density%≤45≤45≤45≤45≤45≤45≤45≤45≤45≤45Slurry specific gravityt/m3≤1.4≤1.4≤1.4≤1.4≤1.4≤1.4≤1.4≤1.4≤1.4≤1.4PH valueAout 1Aout 1Aout 1Aout 1Aout 1Aout 1Aout 1Aout 1Aout 1Aout 1(NH2)2CS Densityg/l6 186 186 186 186 186 186 186 186 186 18Motor powerkW111522 3722 3737 11037 11037 11037 11037 11037 100 This equipment used for the bio-oxidation of refractory leachable gold concentrate containing arsenium ------thiourea RIP gold extraction processing method
