Abstract
Provided is a method for removing arsenic from copper smelting soot and comprehensive recovery of valuable metals. According to the method, a metal leaching synergist is prepared through thiol-ene click chemical reaction, which is capable of reacting more effectively with arsenic and metal impurities in the copper smelting soot due to its special chemical structure, thereby improving leaching efficiency; and the cage-like structure of the polysilsesquioxane provides excellent chemical stability, the removal rate of harmful substances in the copper smelting soot can be increased by using the synergist, environmental pollution is reduced, meanwhile, the recovery rate of metal resources is increased, and the requirements of green chemistry and sustainable development are met. The present disclosure realizes the centralized management of As and also realizes the step-by-step recovery of valuable metals such as Cu, Zn, Pb, Bi, and In.
