Rock wool insulation is composed principally of fibers manufactured from a combination of aluminosilicate rock (usually basalt), blast furnace slag, and limestone or dolomite. Slag is a byproduct from steel production that would otherwise wind up in landfills. Binders may .
Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten ...

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
More than 400 million tonnes of iron and steel slag is produced each year. Slags are a mixture of silica, calcium oxide, magnesium oxide, and aluminium and iron oxides. During smelting, slagging agents and fluxes (mainly limestone or dolomite and silica sand) are added to the blast furnace or steelmaking
