Investigation of Getting Iron Dust from Iron-Sulfide Concentrate

Abstract
In the paper we investigate process of getting iron dust form iron-sulfide polymetallic concentrates. Overall, a mechanism for extracting iron is suggested along with most optimal modes. The mechanism is made up from the following processes iron-sulfide concentrates roasting, dissolution of sulphate extract from a weak sulfuric acid solution, hydrolysis of trivalent iron and iron oxide extraction from sulfate-acid solution and finally electrolysis of iron divalent sulfate to obtain iron dust. The result is iron dust with 98.5 - 99.0%purity. Keywords - Iron Dust, Trivalent, Divalent, Sulfate
