Granulated blastfurnace slag is produced by quickly quenching (chilling) molten slag to produce a glassy, granular product. The most common process is quenching with water, but air or a combination of air and water may be used. Very little mineral crystallization takes place in the very rapid cooling process. The granulated slag may vary from a

Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. 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
slag on the open market, and pays a small percentage of the net slag sales revenues or profits to the iron or steel company. Slag can be returned to the furnaces for use as flux and as a supplemental source of iron, but despite having a value, this return flow is commonly not included in the tonnages of slag reported as sold.
