Recycling an Industrial Byproduct. Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.
Nickel slag is a solid waste produced from smelting ferronickel alloy. Ferronickel alloy is mainly used for stainless steel production, so nickel slag is also called stainless steel slag or nickel iron slag. Nickel slag powder can be used as mineral admixture for concrete, .
Aug 01, 2018· 1. Introduction. Steel slag is the oxidized material that is generated when lime, dolomite, and other auxiliary materials are added, and oxygen is blown onto the pig iron produced by a blast furnace to remove carbon (C), phosphorus (P), sulfur (S), and other components to produce crude steel in a basic oxygen furnace (BOF).

Steel recycling generates a small water impact. This impact is due to steel production from sources generating blast furnace slag which in turn is used in concrete production as a substitute for cement. When recycling is undertaken, this process no longer occurs, so concrete production must revert to cement in place of blast furnace slag.
