Chelsea Williams等人提出了一种酸浸混合镍钴氢氧化物沉淀物(MHP)的新方法。采用此法,通过优先氧化,镍和锰留在固相,而大部分镍被溶解。介绍了有关的氧化反应热力学。温度在30~80℃范围内,浸出前MHP的老化时间对金属提取和浸出动力学没有明显影响。溶液中的主要杂质为钙和
Chelsea Williams et al. Proposed a new method for acid leaching mixed nickel cobalt hydroxide precipitates (MHP). With this method, nickel and manganese remain in the solid phase by preferential oxidation, and most of the nickel is dissolved. The related oxidation reaction thermodynamics is introduced. The aging time of MHP before leaching had no obvious effect on the kinetics of metal extraction and leaching at the temperature of 30-80 ℃. The main impurities in the solution are calcium and
