Nov 01, 2017 · Flux (limestone) acts as the chemical cleaning agent, absorbing the iron impurities and leaving behind molten steel. The result is separate levels of slag and molten steel…
Slag-What is it Good for? - USGS
We looked specifically at ferrous slag, the leftover material from the smelting of iron and steel, in the Chicago-Gary area of Illinois and Indiana. Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded.
Slag Contractor – Slag Removal - Steel Mill Services
Stein is able to reclaim scrap that is high in metallic content. We accomplish this through the use of scrap / slag separator plants which are custom designed to satisfy the requirements of each steel operation we service. The reclaimed metallic scrap is returned to the steel making and iron making facilities or sold externally by Stein.

PDF Iron and Steel Slag Utilization: A Comprehensive Analysis
2.2 Characteristics of iron/steel slag The typical compositions of iron/steel slag are shown in figure 1. The exact composition of iron/steel slag varies with the type of furnace used, type of steel grades used and the pre treatment method. Steel and iron slags primary components include limestone (CaO) and silica (SiO2).
Generation of iron and steel slag : NIPPON SLAG ASSOCIATION
Blast furnace slag is a combination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered.
