Strengthening pelletization of manganese ore fines containing high combined water by high pressure roll grinding and optimized temperature elevation systemZHU De-qing(朱德庆)1, YU Wei(余为)1, 2, ZHOU Xian...:Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely......
) and chemical manganese dioxide (MnO2) served as the raw materials. On preparing Li-doped spinels, raw materials with various nominal Li/Mn ratios (0.45 to 0.70) were mixed and ground carefully, then preheated... samples, and this plateau has a tendency to emerge at higher voltage region with increasing Li/Mn ratio. Key words: lithium manganese oxides; spinel; LiMn2O4; Li2MnO3; cyclic voltammetry
