Abstract

 
 
 When ferroalloys are produced, a large number of coproducts are also formed: slag, riddlings of small fractions of ore raw materials and finished products (ferroalloys), sludge, dust and a number of other materials. Their use and processing allows for reduced consumption of the original minerals, thereby increasing the efficiency of the main production and reducing environmental pollution. As a result, both enterprise costs in the form of environmental payments for emissions and waste disposal, as well as government costs associated with environmental measures are reduced. However, the scale of use of ferroalloy production wastes is relatively small. The replacement of the main and auxiliary equipment with new, environmentally friendly equipment, can promote to significantly reduce or completely eliminate hazardous emissions and the generation of unclaimed production waste. It is necessary to organize the use of blast furnace gas from ore reduction furnaces for preheating and partial recovery of elements of charge materials.

Highlights
The waste of any metallurgical production is associated with the under-exploitation of raw materials in the process
The deterioration in the quality of natural mineral raw materials, lowering the leading elements in it leads to an increase in the loss of materials and waste
This applies to ferroalloy production [1], where the low degree of use of valuable elements of alloys is associated with their losses at all production stages of raw materials
