摘要
A method for concentrating iron by comprehensively utilizing steelmaking dust: steelmaking dust is mixed with a reducing agent, an additive and water, is pressed into balls which are dried and then baked in vacuum, and a volatile substance and solid residue are collected. The volatile substance is elemental zinc in the gas phase, which is fed into a condensation collector and then condensed into a solid; the solid residue is broken and ball-milled, then pickled to remove impurities in a residual iron phase to obtain iron concentrate. Processing parameters are controlled, while the recovery rates of iron and zinc are increased.
