Optimization of magnetic separation process for iron

2017-2-1  To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (M-Fe) in the slag.

The Role of Molten Slag in Iron Melting Process for

2010-8-15  The behavior of the molten slag was clarified by direct observation of phenomena occurring in a simplified carbon composite agglomerate sample (iron disk–slag particle–graphite or coke particle) via a confocal laser scanning microscope combined with an image furnace. It was found that the molten slag wetting induced the iron melting initiation by attracting graphite or coke to iron and the molten slag separation took place with iron

STUDY OF IRON AND STEEL SLAG AS A PRODUCT WITH

2017-3-4  Steel making process in electric arc furnaces generates up to 15 % of slag per ton of steel. Major components of steel mill slag include Ca-silicates, Ca-Al-ferrites, and molten oxides of calcium, iron, magnesium, and manganese. The composition of slag varies upon the type of furnace and charge, the desired grade of steel purity and the furnace operation conditions. Materials to be added to the steel melt directly before the end of the reheating process are not fully embedded in the slag structure, so they can be found in the slag as “free“ oxides (CaO, MgO). Compared to blast furnace slag, steelmaking slag shows a considerably higher content of iron, manganese, and magnesium along with the lower silicon content i.e. higher CaO/ SiO2 ratio, and, finally, it contains almost no sulphur at all. Steel mill slag
