Super-Grade Iron Concentrate Experimental Study on an Iron Concentrate from Sichuan
In terms of the iron concentrate, the TFe grade is 65.50% and mainly gangue is quartz with the content of 4.82%. Additionally, the content of harmful impurity, sulphur and phosphor, is low.

| description | In terms of the iron concentrate, the TFe grade is 65.50% and mainly gangue is quartz with the content of 4.82%. Additionally, the content of harmful impurity, sulphur and phosphor, is low. Following grinding-magnetic separationis able to enhance the mFe content and grade of concentrate for the reason that the content of mFe is 98.74% and other iron phase is nonmagnetic. The process of prescreening-grinding-classification-magnetic separation-reverse flotation is adopted to the super-grade iron concentrate experimental study of an iron concentrate from Sichuan. When the screen size is 0.074 mm and grinding fitness is -0.038 mm 90%, using the thenanoceramic balls as milling medium, super-grade iron concentrate with yield 24.23%, TFe grade 71.71%, quartz content of 0.16%, acid insoluble content of 0.16% could be obtained. In the process, the usage of corn starch is 600 g/t and the usage of collector is 100+50+50 g/t. The process is reasonable and significantly feasibility with low energy consumption and simple reagent system. Additionally, the process could obtain normal iron concentrate with the yield of 72.25% and TFe grade of 65.47% which could be considered as good iron concentrate product to sell. |
