Metallurgical waste can be recycled using a new method
[ad_1]
Students and young scientists of the MISIS University have developed a technology for processing waste from metallurgical industries, which makes it possible to extract almost 98% of valuable components from this waste. In addition, the technology speeds up waste processing by 2-6 times compared to existing methods.
As explained by the authors of the invention, during the smelting of steel in furnaces, tons of dust are formed, which includes oxides of various elements. These elements enter the environment, causing serious harm to the environment. The new method of MISIS specialists allows processing this dust, extracting iron and zinc from it for their subsequent use.
According to one of the authors of the study, an employee of NUST MISIS Valentin Romanovsky, waste from electric arc furnaces was used as the feedstock. By special heat treatment, zinc oxide was isolated from them, the content of which in the extracted substance was 98.4%, the iron content in it was 97.5%.
