Study and design of mineralization of arsenic sulfide slag of smelting hazardous waste
When High-quality copper concentrate resources are increasingly tight,copper smelting enterprises gradu-ally increase the proportion of raw materials containing arsenic and other impurities,and the resource recovery and harmless disposal of arsenic-containing materials in the smelting process has become an urgent problem to be solved.Fire method,wet method and comprehensive method are the main technical methods for the disposal of arsenic-con-taining materials.Among them,the wet disposal is mainly produced in the form of arsenic-containing arsenic sulfide residue,which is characterized by high water content,large storage capacity and low utilization rate.In this paper,arsenic sulfide residue is taken as the research object to study the mineralization under different liquid-solid ratio,temperature and pressure,so as to realize the precipitation and storage capacity,and carry out industrial idea design to improve its utilization rate.
