On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) the iron ore is crushed and the waste rock is removed. about 85 % of the particles should be less than 44 μm (in length, width, or height). it is then possible to extract the valuable mineral, which is.
Prior oxidation of magnetite ore to fe 2 o 3 leads to similar reduction behavior when compared with natural hematite; however, natural magnetite is hardly reducible due to low porosity and the formation of dense intermediate products during the reduction. 8) accompanying oxides in the iron ore, such as alumina, influence the reduction.
