Beneficiation of Iron Ores – IspatGuru
Spirals require addition of water at various points down the spiral to assist washing of the iron ore, i.e. transporting away the light gangue from the dense ore. The amount of wash water and its distribution down the spiral trough can be adjusted to meet the operating requirements.

iron processing
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is
