Abstract: With the development of industry, arsenic pollution has become a global environmental problem. Especially in the metallurgical chemical industry, the output of arsenic-containing waste slag is huge and harmful, and the treatment of arsenic-containing waste slag needs to be solved urgently. The main sources, hazards and current status of arsenic-containing arsenic are introduced in this paper. The treatment methods of arsenic-containing slag at domestic and foreign are introduced in detail, including solidification methods such as cement solidification and geopolymer solidification, as well as resource processing methods such as acid leaching and copper sulfate replacement. Which is intended to provide useful help for the future research on the treatment of arsenic-containing waste residue.
