Experimental Study on Washability of a Magnetite Ore in Shandong
In order to verify the feasibility of separation and utilization of a magnetite ore in Shandong Province in the beneficiation process of Zhongguan Iron Mine,based on the study of ore properties,the grindability and washability test of the iron ore was carried out.The test results show that taking Zhongguan iron ore as standard ore,the relative grindability coefficient of an iron ore in Shandong is 1.20 when the grinding fineness is 50％ of the new-0.074 mm fraction,which is more difficult to grind than that of Zhong-guan iron ore.When the grinding fineness of an iron ore in Shandong is -0.074 mm 82.18％,the satisfactory indexes of yield 72.72％,iron grade 66.28％ and iron recovery 97.08％ can be obtained by single low intensi-ty magnetic separation.However,the sulfur content in the iron concentrate is high,which is 0.69％ and needs further treatment.The test results can provide a reference for the selection and utilization of a magne-tite ore in Shandong in the beneficiation process of Zhongguan Iron Mine.
