Abstract

Summary

Most industrialized advanced countries of the world place high emphasis on utilization of mining wastes. In Ukraine, rate of waste recycling still remains rather low. All the industrial wastes of Ukraine can be classified into four main groups which differ on amount of accumulated materials, hazardous rate and valuable components present. Mining enterprises of Ukraine produce two types of wastes – overburden rocks accumulated in dumps and slimes stored in tailing ponds.

Kryvyi Rih iron ore basin of Ukraine may be taken as a typical example, where 10 to 13 bln tons of overburden rocks are accumulated in dumps. The dumps include about 50 useful minerals and rocks that might be recycled. Unlike dumps placer deposits can be formed in tailing pond. there are several types of technogenic placers that can be worked out in Ukraine: (1) iron ore tailings (500 mln tons) to be recycled on iron and gold (up to 4 g/t); mangane ore tailings (150 mln tons); (3) alumina red slimes (1,2–1,3 mln tons) that include gold, zircon and rutile grains; (4) tailings of titanium ores to be recycled on gold (5–6 g/t); (5) tailings of kaoline that might be recycled on monazite concentrate (lanthanides and thorium).”
