Experimental Study on Bioleaching of Low-grade Molybdenum Tailings AITranslate
Abstract AITranslate
Experimental study was carried out on bioleaching of very low-grade molybdenum tailings with acidithiobacillus ferrooxidans and moderately thermophilic sulfobacillus sibiricu,respectively.The influences were investigated of the presence and type of bacteria on molybdenum tailing leaching.Molybdenum concentration in the leaching solution was measured by ICP,and its redox potential was determined by pH meter.The leaching residue was characterized by XRD and SEM.The results show that both the two bacteria bioleaching processes are effective for very low-grade molybdenum tailings of 5%slurry concentration.The presence of bacteria is beneficial to leaching of molybdenum tailings.Sulfobacillus sibiricu has better leaching results of molybdenum tailings,and its molybdenum leaching rate is 18%after 23 dleaching while acidithiobacillus ferrooxidans has only 8% molybdenum leaching rate.
