摘要
本文介绍用7%ZnSO_4·7H_2O浸取分离金属Mn,残渣再用40%(NH_4)_2SO_4浸取分离MnO和Mn_3C合量,最后以H_2SO_4+HNO_3溶解残渣测定除MnO外的Mn的氧化物,使各含Mn相的分离与测定获得较满意的结果。
The composition of this ore under investigation is a-Mn, Mn-oxides, Mn-carbides and various Fe-compounds. This paper introduces the phase analysis of Mn compounds. The metallic manganese can be extracted in zinc sulfate solution and determined volumetrically. After MnO and Mn-carbides are extracted with (NH4)2SO4 solution, the residue is used to determine the other Mn-oxides.
