Processing of Granulated Blast Furnace Slag and its

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.

Research for the Processing of Stale Slag from the Ural

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.
