Making Slag - an overview | ScienceDirect Topics

2010/04/05 · Iron making in the BF produces a slag that amounts to 20–40% of hot metal production. BF slag is considered environmentally unfriendly when fresh because it gives off sulfur dioxide and, in the presence of water, hydrogen sulfide and sulphoric acid are generated. These are at least a nuisance and at worst potentially dangerous.

Metal Recovery from Steelmaking Slag

temperature, slag basicity, and magnetic field strength on recovery and grade of the concentrate were investigated and optimized oxidation of iron mono-oxide (FeO) to magnetite (Fe 3

Types of iron and steel slag : NIPPON SLAG ASSOCIATION

Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

Iron and Steel Slag Utilization: A Comprehensive Analysis

Steel making slag is a byproduct from steelmaking processes in which the components of pig iron and steel-scrap are modified in order to produce steel that is highly valued for toughness and workability.

The potential utilization of slag generated from iron- and ...

2019/10/29 · Along with iron and steel production, large amount of slag is generated. Proper management on the iron- and steelmaking slag is highly demanded due to the high cost of direct disposal of the slag to landfill, which is the most adopted management approach. In this article, the potential application of iron- and steelmaking slag has been reviewed, which included the slag utilization in ...

Recycling Effects of Residual Slag after Magnetic Separation ...

If most of the phosphorus can be removed from the slag, the residual slag will comprise FeO–CaO–SiO 2 –MnO–MgO with less P 2 O 5, and thus may be recycled to iron- and steel-making processes, such as sintering, hot-metal

Iron processing | Britannica

2020/08/14 · Cort used a coal-fired reverberatory furnace to melt a charge of pig iron to which iron oxide was added to make a slag. Agitating the resultant “puddle” of metal caused carbon to be removed by oxidation (together with silicon, phosphorus, and manganese).
