Development and Design of the First Industrial Magnetohydrodynamic Slag
The future challenge for copper smelters is to increase metal yield by reducing copper losses and valorizing the slag as a marketable by-product. This can be achieved through further slag cleaning in a conventional submerged arc furnace (SAF) where remaining metallic oxides are reduced, and metal droplets have more settling 11ügranulated slag Figure 2. INBA process. 4 Dry granulation process On the blast furnace slag treatment technology, for a long time, water quenching process has token the leading position. However, there are many defects of water-quenching slag method, which can be roughly concluded as follow: a mass of sensible heat unrecovered, A Review of Granulation Process for Blast Furnace Slag

Slag foaming estimation in the electric arc furnace using
1. Introduction. Electric arc furnace (EAF) steelmaking is an eco-friendly process, which recycles end-of-use scrap metal and constitutes approximately 30 pct. of the 1.8 billion tons of steels produced globally [1, 2].Within the EAF steelmaking process, slagmaking is essential in absorbing impurities such as sulfur and phosphorous during During the mechanical slag processing by Loibl the slag is treated and sorted in several process steps. Ferrous and non-ferrous materials as well as ashes and slags are separated with suitable separation units such as screens, ferrous and non-ferrous metal separators and wind sifters.
