What's the process of iron ore mining? Jan 20 2017The first step involves the iron ore is crushed into small pieces The obtained crushed ore in the send to the grinder followed by the scrubber The major task of the scrubber is to remove waste from the ore and then categorize it into the sizes i e oversize midsize and undersize This is the process involved in iron ore mining

Addition of dispersant significantly improved the separation efficiency. The maximum iron grade and recovery predicted by the model is 65.0% and 60%, respectively, for a iron ore slime sample containing 57.84 Fe, 6.0% Al2O3, and 6.7% of SiO2.
