Sustainable Mining and Metallurgy

The roles of bulk auxiliary materials in the production process, including quartz sand, quick-lime powder, hydrogen peroxide, barium sulfate, industrial sodium sulfate, limestone, etc., were elaborated in this article, and effects of quality and dosage variations of auxiliary materials on production were analyzed. Auxiliary materials are applied in the smelting industry for stabilizing furnace conditions, slagging and impurities removal, improving product quality, recovering valuable metals, increasing recovery rate, protecting the environment and other purposes. There are many kinds of such auxiliary materials in great demand, so a sound quality control system for auxiliary materials should be built in production.
