The content of sulfur in the sulfide ore can be decreased by microbial desulfurization.The effects of pH,inoculum concentration,pulp density and original Fe2+ concentration on desulfurization have been investigated by shake flask experiment.Regression analysis was used for solution potential and desulfurization degree.The results show that pH has the largest contribution to desulfurization.The optimization condition of microbial desulfurization were pH of 1.5,pulp density of 5%,original Fe2+ concentration of 0,inoculum concentration of 10%.At the conditions,the maximum expected value of solution potential was 804 mV,and desulfurization was 22.7%.
