iron ore slag recycle

The reuse of slag for the extraction of iron oxides, besides allowing the use of potentially polluting material, allows its strategic use in biotechnological applications. For this it is necessary a characterization of the slag as the proportion of iron oxides to …

RECYCLING IRON CONSERVES ENERGY AND SAVES LANDFILL SPACE. It takes less energy to create iron and steel from recycled iron than from iron ore. Using recycled metals also helps mitigate some of the negative effects of the mining process, which is energy- and water-intensive and does lasting damage to the areas surrounding mines.

Using ore (including man-made rich ore or concentrate, etc.) as raw materials for reduction smelting or oxidation smelting, the slag formed while obtaining coarse metal or matte is called smelting slag. The slag produced by refining crude metal (smelting steel with pig iron, refining copper from blister copper, etc.) is called refined slag.

Their production arises from the conversion of ores to iron, hot iron to steel, and from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. These by-products, especially in the past, were classified as waste and often stocked and or disposed in landfills, although they could be a valuable secondary raw material when recycled and …

The way that the slag has been cooled can have an influence on the amount of metallic iron that can be recovered from the slag (Wang et al., 2012). The magnetic separation process and the crushing process are often repeated several times to increase the amount and quality of metallic iron that can be recovered from the process ( Horii et al., 2013 ).

10.2.2 Blast furnace slag Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.
