  • Methods of granulation of molten slag and use of

    Nowadays, most of the blast furnace slag is processed into granulated slag, which is a valuable recyclable material used in the construc-tion industry. The production of granulated slag is high energy consumption, requires a large amount of water and causes environmental pollution since in the process of granulation hydrogen sulfide gas is formed.
