manufacturing process of sinter from iron ore dust

Sinter production - Praxis Engineering

Sinter production Process of baking sinter at the furnace grade. Sinter production is one of processes of metallurgic production during which concentrated ore (or upgraded ore) sinters due to thermal processes and flux materials (usually crushed limestone) which are called sinter cake and serve as ready material for blast-furnace smelting.
