27/10/2011 In the earliest processes the slag consisted mainly of the impurities (known as the gangue) that were present in the iron ore; in more modern times there is also a large contribution from materials added to aid the underlying process or to remove some specific deleterious element. An early example of this was the lime added to the feed for blast furnaces to give a more fluid slag, to reduce ...

Among the commodity metals, iron and steel are by far the most widely used materials with annual production near 1.9 billion metric tons. 3 The main byproduct of ironmaking is iron slag, so-called blast furnace (BF) slag, which is generated when iron ore is mixed with flux (limestone and/or dolomite) and coke for fuel and heated under reducing conditions at above 1500 °C, producing molten ...
20/08/2019 It is concluded that the magnetic separation is more effectively to remove the iron impurities from the initial content of 5.68% to the final content of 0.48%. Up to now, little research work has been done on the separation of silicon from the waste silicon slag. In this paper, a short process for the recovery and purification of metallic silicon from waste industrial silicon slag has been ...
01/11/2019 As a valuable byproduct of the iron-making process, blast furnace slag with temperature up to 1450–1650 ° C contains a tremendous amount of sensible heat. Dry granulation and waste heat recovery via a moving bed is an attractive alternative to the conventional water quenching method due to energy-savings and the reduction in water consumption. In this study, the extended discrete element ...

Induction furnaces are normally kept open during the entire melting process where the workers engage in slag skimming and monitoring of the quality of molten bath. However, this leads to significant heat loss and hence special covers or lids need to be installed for reducing heat losses. In particular, reducing the time the lid is kept open while melting, can lead to substantial energy savings.
