Processing of Granulated Blast Furnace Slag and its
The most common process for granulating blast furnace slag involves the use of high water volume, high pressure water jets in direct contact with the molten blast furnace slag at a ratio of approximately 10 to 1 by mass. The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a 4 sieve.

Blast Furnace Slag an overview ScienceDirect Topics
Blast furnace slag BFS is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.
Iron and Steel Slag Statistics and Information
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
Research for the Processing of Stale Slag from the Ural
Pyro-metallurgical copper production is characterized by the formation of a large amount of slags. The copper content in the smelt slag is 0.5-2 , in the vessel slag - about 5, which often exceeds the copper content in the mined ores about 1. This makes depletion of slag a necessary operation in the pyro-metallurgical production of copper.
