Slag type optimizing agent in copper smelting process and preparation method of slag type optimizing agent

Abstract

The invention discloses a slag type optimizing agent. The slag type optimizing agent comprises 25%-30% by weight of Al2O3, 20%-30% by weight of SiO2, 15%-20% by weight of Fe powder, 15%-20% by weight of lime and 5%-10% by weight of Na2CO3. The invention further provides a preparation method of the slag modifier. The slag type optimizer provided by the invention has the advantages of low melting point, high melting speed, good slag flowability, strong adsorption and inclusion capacity and the like, so that the slag type optimizer has good effects of regulating slag and improving the adsorption, entrainment and removal of impurity elements such as As, Pb and the like as the slag type optimizer, the output of dangerous waste slag in the copper smelting process is reduced, and the production cost is reduced. Environmental pollution caused by poor stacking of the dangerous waste residues is avoided, and meanwhile, the treatment cost of the dangerous waste residues is reduced. And moreover, the slag modifier is convenient to use, the labor intensity of workers is not increased, and the impurity element removal capacity in the copper smelting process is improved, so that the production cost is reduced.

Description

technical field [0001] The invention relates to a slag type optimizer in a copper smelting process and a preparation method, and belongs to the technical field of copper smelting pyrometallurgy. Background technique [0002] In the past, because enterprises used high-quality copper ore raw materials for copper smelting production, there was usually no problem of excessive As and Pb content, and these impurities could be removed in the electrolytic refining section. With the rapid development of my country's copper smelting industry, high-grade and low-impurity copper concentrates are increasingly scarce. Most of my country's copper ore resources are lean ores and associated ores with low grades. In recent years, with the increasingly complex composition of copper raw materials, the content of As, Pb and other impurities has been increasing day by day, and conventional operations have been unable to ensure product quality. Copper smelting enterprises are faced with the commo...
