Processing And Use Of Solid Technogenic Waste - Damping Metallurgical Slags For Producing Calcium-Containing Ferro-Alloys

Abstract

In the given article there are presented the results of complex calcium-containing ferroalloy from high-ash coals of the Saryadyr deposit, dump blast-furnace slag and slag of refined ferromanganese, which related to technogenic waste. There is established the possibility of smelting calcium-containing ferroalloy, the recovery of basic elements reached 91.56% manganese, 87.75% silicon, 76% aluminum and calcium up to 40% Keywords: high-ash coals, blast-furnace slag, technogenic waste, calcium ferroalloy, smelting IntorductionThe depletion of a number of natural mineral resources, and on the other hand the accumulation of huge amounts of technogenic waste, which containing valuable components, can be considered as alternative sources of natural resources, both in color and in ferrous metallurgy. In addition, involvement in the processing of production waste not only solves the problem of the limited resource base, but also becomes a solution to environmental problems in the region.
