In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.
Recovery of iron from the waste slag is of great interest for maximum use of mineral resource, reduction of environment impact and improvement of economical benefits to the related companies. This paper is mainly focused on the effect of the temperature on recovery of iron from waste slag of pyrite processing using reductionroasting magnetic separation method.
Due to the effects of the limestone it contains, the pH of iron and steel slag increases to 10 – 12 when it reacts with water, indicating alkalinity that is the same or lower than that of recycled concrete base course material and cementstabilized soil.

AirCooled Blast Furnace Slag. Crushed ACBFS is angular, roughly cubical, and has textures ranging from rough, vesicular (porous) surfaces to glassy (smooth) surfaces with conchoidal fractures. There can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.

This emulsion of slag particles remains stable if the molten iron is continuously agitated, as in the case of the magnetic stirring inherent to induction melting. Until the nonmetallic particle size increases to the point where buoyancy effects countervail the stirring action, the particles will remain suspended.
