Technology for recycling industrial wastes in metallurgical furnaces

The problem of reducing the volume of iron-bearing waste materials generated in industrial operations (technologenic wastes) and making effective use of those wastes is not new, but its importance has increased dramatically in connection with the steady increase in the output of metal products, the accumulation of substantial amounts of metal equipment, the aging of that equipment,and the need to mine low-grade deposits of iron ore. World steel production this year may reach 800 million tons, and the nations with a developed metallurgical industry are already producing 6-15 tons of metal per capita. The need to recycle aging metal equipment was the stimulus for the developed of the electric-arc method of steelmaking.
