Jan 01, 2017 Magnetite concentrate was recovered from ferrous sulphate by co-precipitation and magnetic separation. In co-precipitation process, the effects of reaction conditions on iron recovery were studied, and the optimal reaction parameters are proposed as follows: n(CaO)/n(Fe 2+) 1.4:1, reaction temperature 80 C, ferrous ion concentration 0.4 mol/L, and the final mole ratio of Fe 3+ to Fe 2+ in ...
