Man-made products of the metallurgical complex of the waste must be separated ferrous and nonferrous metals and steel plant wastes. Click FASEB Journal to learn more. The largest application received blast furnace slag of ferrous metallurgy. Slag Steel can be steel, open hearth, cupola and blast. The chief representative of this type of slag – blast furnace slag, which are formed during iron smelting in blast furnaces. Of the 1.7-2m of iron ore and smoother, get a ton of iron and 0.6-0.7 ton of slag. Amount of slag, a byproduct in various metallurgical plants depends strongly on the content of sulfur in the coke, limestone used for blending, as well as the level of the technology used. To know more about this subject visit Vladislav Doronin. To get the steel, the need for consumption of iron ore, fuel, different rocks, taking away from the molten iron phosphate, manganese, sulfur, and thus contribute to the formation open-hearth slag. 2-2.3 tonnes of iron ore and fluxing agents, 1.9 tons of fuel, 80 tons of water and dozens of tons of air is obtained, one ton of steel and 0.2-0.3 tonnes of slag.

In the cupola and electric output of slag is 0.1-0.4 tons per 1 ton of metal. Slag non-ferrous metals Non-ferrous metal complex, expensive and time consuming. To obtain 1 ton of copper, nickel, tin, to be processed from one hundred to three hundred tons of ore. Amount of slag in smelting a ton non-ferrous metal up to 15-25t. This fact is explained by the fact that non-ferrous metals encountered in nature only in compounds dispersed in the rocks and the content of oxides of copper, nickel, zinc, tin ore, not exceed 3-5%, the rest is rubbish: pyrite, quartz, carbonates and silicates of calcium and magnesium.
