The article presents technological solutions for the formation and utilization of microsilicon dust formed in the filters of gas purification plants for the production of siliceous alloys. The paper provides convincing arguments for the separation of dispersed dust and mass losses and shows ways to recycle man-made waste from ferroalloy production. The scope of application of dust accumulating in a pile and stored in big bag bags is not fully provided. One of the solutions to the environmental problem can be the work carried out in the article. The results of laboratory studies show the results of primary studies on the extraction of silicon carbide from microsilicon dust. A research work on the loss of dust mass was carried out in the Tamman high-temperature furnace, and specific causes of mass loss were identified. A sufficient amount of silicon dioxide in the dust can be a source of silicon to produce silicon carbide, which makes it possible to obtain a product using a low-carbon reducing agent. The use of neftekox as a reducing agent corresponds to the trend of obtaining silicon carbide using traditional technology. The article provides prerequisites for the production of silicon carbide using silica instead of quartz sand. Due to solid and gas-phase synthesis, mass loss indicators are considered an important physico-chemical characteristic of charge materials.
