Abstract
Generation of technogeneous waste in production of ferroalloys and possible solutions for recycling are presented in the article. A lot of by-products are generated at the stage of ferroalloy production: slags, raw materials and ferroalloy fines, sludge, dusts and some other materials. Chemical composition and quantities of slags, dusts and sludge in production of manganese, chromium and silicon alloys are given. Ferroalloy production waste can be recycled in ferroalloy production process or allied production chains. Possible applications of technogeneous raw materials in ferroalloy and allied production technologies are considered. Involvement of ferroalloy production waste into ferroalloy production technology requires deliberate decisions, as performance characteristics of furnaces in ferroalloy production depend on quality of raw materials (manganese ores, chromites, etc.). It is proposed to find a recycling solution on the basis of precise estimation of physic-chemical characteristics of materials.
