process that combining alkaline multistage oxidation leaching and hydrochloric acid leaching was used to pretreat lead anode slime. When lead anode slime was leached by alkaline multistage oxidation..., are applied to strengthen the NaOH leaching procedure. When H2O2 is added to strengthen NaOH leaching, the base metals in lead anode slime can be removed efficiently. The leaching ratio of arsenic can reach 92......
