Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production.


Aluminium salt slag recycling. Eddy current separators enable efficient recovery of the aluminium granules of aluminium salt slag. Since most of the aluminium is present in the fine and ultrafine <3 mm fractions, particularly high-frequency, specially adapted STEINERT EddyC® non-ferrous metal separators must be used.


The main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined mined a year - about 95 percent is used by the steel industry. Iron ore is the world's third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - only beaten by crude oil.


3 Iron Unit Recycling On a weight basis, steel is the most recycled material in use today (Figure 3-1). The 70 million net tons of steel recycled in 2000 were used to produce about 112 million net tons of new steel in the United States.
