Experimental Study on Optimization of Grinding and Mineral Processing of Meishan Iron Mine
In order to reduce the production operation cost and further increase the ore processing ca-pacity,the beneficiation optimization test was carried out on the grinding of Meishan Iron Mine.The two pro-cess schemes of grinding(grinding fineness-0.075 mm accounted for 65%)-floating sulfur-sulfur tail low intensity magnetic-high intensity magnetic process(scheme 1)and grinding coarse grinding(grinding fine-ness-0.075 mm accounted for 50%)-gravity magnetic pulling tailings-gravity magnetic pulling concentrate regrinding(grinding fineness-0.075 mm accounted for 65%)-floating sulfur-sulfur tail low intensity mag-netic-high intensity magnetic separation(scheme 2)were compared respectively.The experimental results show that by the process of scheme 2,the iron concentrate with yield of 49.88%,TFe grade of 58.29%,sul-fur content of 0.20%and TFe recovery of 77.89%,and the sulfur concentrate with yield of 1.81%,sulfur grade of 38.11%,TFe grade of 45.44%and sulfur recovery of 49.62%are obtained.The economic and tech-nical indicators are good,which can provide a basis for actual production.
