:A Extraction of TiO2 from high titanium slag through roasting by ammonium bisulfate SUI Li-li1, 2, ZHAI Yu-chun1 (1. School of Materials and Metallurgy, Northeastern University, Shenyang 110819, China... analyzed. Through single factor experiments, the effects of material particle size, mass ratio of ammonium bisulfate to ore, roasting temperature and roasting time on the extracting rate of TiO2 were......
. The phases of zinc and iron from ZLR were adjusted by roasting with ammonia sulfate before zinc was leached selectively with water. The effects of various parameters, such as ammonium sulfate addition, roasting temperature and time on decomposition rate of zinc ferrite and extractions rates of zinc and iron were investigated. The optimal experimental conditions are gotten as follows: ammonium sulfate......
. For the solution with an ammonium concentration below 3 mol/L, the separation factor is high due to the high W-precipitation rate. Furthermore, the method is also effective when it is applied to industrial...; ferrous sulfate 1 Introduction As a consequence of the lanthanide contraction, Mo and W have almost identical atomic radii and analogous electronic structures, and hence exhibit extremely similar......
