Taking the electrolytic manganese anode slime as the research object,this paper conducts experiments of high-temperature roasting and leaching with ammonium acetate solution on materials sequentially after pretreatment.At the same time,before and after roasting process,the samples are leached and characterized by scanning electron microscopy(SEM).Additionally,the paper studies the leaching behaviors of lead ions existing in the electrolytic manganese anode slime,and carries out single factor experiments to ...
