sodium sulfate magnetic separation

May 01, 2016 The effect of sodium sulfate on direct reduction of beach titanomagnetite, followed by magnetic separation, to separate iron and titanium was investigated. Direct reduced iron (DRI) with a high Fe content, low TiO2 content and low iron recovery was obtained after adding sodium sulfate

    Sep 10, 2013 A high nickel grade ferronickel was produced from laterite ore using the selective reduction-wet magnetic separation process, with the addition of sodium sulfate (Na 2 SO 4). The ferronickel concentrate assaying 9.87% Ni, with a nickel recovery of 90.90% can be obtained, when laterite ore was reduced at 1200 C for 50 min with the addition of 10 wt.% Na 2 SO 4 and 2 wt.% coal

    Dec 10, 2014 Sodium sulfate addition caused the formation of FeS, which was closely related to metallic iron grains that were difficult to completely remove by magnetic separation. The residual FeS in the DRI was oxidized to Fe–S–O-bearing material during the process of mineral processing and was still closely associated with the metallic iron
