2/24/2015· The majority of steel production is supported by iron ore sourced from high-grade hematite deposits, although a significant fraction comes from magnetite deposits. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix.

Summary of Iron Ore Beneficiation Process and

Because of the simple composition of ore, weak magnetic separation is often used. For large and medium-sized magnetic separation plants, one-stage grinding magnetic separation is often used when the grinding particle size is greater than 0.2 mm. When it is less than 0.2mm, two-stage grinding magnetic separation is adopted.

Introduction to Iron ore Pellets and Pelletizing processes

The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is required for the pellet production. Suitable binder (normally bentonite) is added to the concentrate which is thoroughly mixed in high intensity mixer.
