Problems solved by technology

Due to the large difference in sulfur taste, it is difficult to form a large-scale long-term continuous treatment method that can adapt to various solid tailings. Some of them can be treated by using the sulfur recovery process. However, due to the large investment, small scale, and low sulfur recovery rate, the treated materials The sulfur content is still very high, which cannot meet the requirements for the recovery of organic metals

Abstract

The invention belongs to the technical field of metallurgical and chemical processes, and particularly relates to a treatment system for smelting high-sulfur-content tailings. The treatment system for smelting the high-sulfur-content tailings comprises a raw material supply system, a pretreatment system, a reaction system, a smoke treatment system and a dry material bin. According to the treatment system for smelting high-sulfur-content tailings, the process is smooth, the structure is complete, and the requirement for large-scale continuous treatment of various types of high-sulfur-content tailings and mixtures of the high-sulfur-content tailings can be met; and the problems that a large quantity of solid tailings accumulate and valuable metal cannot be recovered easily are solved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and chemical technology, and in particular relates to a treatment system for smelting high-sulfur tailings. Background technique [0002] In the smelting process of nickel sulfide and copper ore, some solid tailings will be produced after electrolytic separation of nickel and copper, including chlorine leaching residue, hot filter residue, anode slime, etc. These tailings are rich in nickel, copper, sulfur and precious metals. High recycling value. After a long period of accumulation, the total amount of these solid tailings is increasing, and it continues to be produced every year, and its accumulation and storage has become a major problem. Due to the large difference in sulfur taste, it is difficult to form a large-scale long-term continuous treatment method that can adapt to various solid tailings. Some of them can be treated by using the sulfur recovery process. However, due to the large ...
