摘　　要：对电解金属锰阳极泥的性质进行了初步分析,提出了一种将其制备成化学二氧化锰的煅烧氧化法工艺,并对该工艺相关的影响因素进行了研究分析。通过最佳条件实验,制得了视比重为1.61 g/cm3,以γ-MnO2为主的初级化学二氧化锰。如将其进一步精制,可以作为电池级的化学二氧化锰应用。研究表明采用煅烧氧化法将锰阳极泥回收制备成化学二氧化锰的路线是可行的。In the article we analyzed the manganese anode slime,a new method was put forward that the slime was produced into Chemical Manganese Dioxide.At the time the related influenced factors and theory was studied.By the optimum test,we get the crude MnO2,which tapping density is 1.61 g/cm^3 and its crystal structure is mostly γ-type.if it is densitied,the end product can be used in battery.The results revealed that the method is ok which the anode slime can be made Chemical Manganese Dioxide by calcination and oxidation.
