Slag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case, the slag is termed synthetic. Visa mer 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 Visa mer 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 … Visa mer Slags can serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid … Visa mer Slags are transported along with slag tailings to "slag dumps," where they are exposed to weathering, with the possibility of Visa mer 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 calcium, magnesium, silicon Visa mer There are three types of slag: ferrous, ferroalloy, non-ferrous slags, which are produced through different smelting processes.
