Abstract
Industrial wastes resulted from production activity of mining, coal and metallurgical enterprises in the Ukraine make considerable amounts. Waste disposal issues became the economic and environmental problems. Demand for solution of environmental problems combined with the urgent need to find additional sources of cheap dense solids for heavy-density media used in coal preparation gives rise to interest into the recycling of technogenic materials from metallurgical enterprises. Metallurgical production wastes were used as research subject. Electric furnace gas treatment slurries at the Krivoy Rog Central Mining Equipment Repair Plant were demonstrated to be polygenic formation of very complex mineral and petrography composition, which has majority of particles consisting of multiple crystalline or amorphous phases of various chemical composition and physical properties. It is found that dry magnetic separation of electric furnace gas treatment slurries from the Krivoy Rog Central Mining Equipment Repair Plant allows separation of high-magnetic iron-bearing product with density of over 5.2 t/m3. Iron recovery to the magnetic product made 73-75%. Conducted researches resulted in solution of the problem of dense solids production from the technogenic material of metallurgical enterprises, which meet the following requirements: water insolubility; mechanical abrasion resistance; chemical non-reactivity with water and products of separation; sufficiently fine size; relatively low cost.
