WebMar 8, 2016 · Slag processors may handle a variety of materials such as steel slag, ladle slag, pit slag, and used refractory material to recover steel metallics. These materials … Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, … See more Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. The major components of these slags include the oxides of See more There are three types of slag: ferrous, ferroalloy, non-ferrous slags, which are produced through different smelting processes. See more Slags are transported along with slag tailings to "slag dumps," where they are exposed to weathering, with the possibility of leaching of toxic elements and hyperalkaline … See more • Calcium cycle • Circular economy • Clinker (waste) See more In nature, iron, copper, lead, nickel, and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the … See more Slags can serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.
