ABSTRACTFerromanganese is one of the most important alloying elements in steel industries. In this work, the production of ferromanganese was carried out using threephase submerged mini electric arc furnace. The effect of slag basicity due to the addition of a various amount of limestone as fluxing agent on this smelting process was investigated.
Slag Used in Rock Wool / Mineral Wool Insulation Products: Health Effects? Slag wool is a manmade vitreous fiber made by spinning slag into insulating fibers. Some rockwool producers use nearly pure recycled steel slag. This topic has moved to MINERAL or SLAG WOOL HEALTH EFFECTS where you can read details.

The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural ironbearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron
