The materials are then fed through a kiln at 2,600º F to produce grayishblack pellets known as clinker. The alumina and iron act as fluxing agents which lower the melting point of silica from 3,000 to 2600º F. After this stage, the clinker is cooled, pulverized and gypsum added to regulate setting time.

The other product that floats over the molten iron due to its relative lightness is called slag. Slag is composed of calcium oxide (CaO), silica (SiO2) and alumina (Al203). Slag is pulverized into a fine powder called ground granulated blast furnace slag and is used in this form as a cementitious component of concrete. D. Fly Ash

Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a nonmetallic product called blast furnace slag.
