Hematite Processing by Flotation

Hematite Processing by Flotation

The fines form a bedding on the conveyor belt, thus increasing its life. Electromagnetic and magnetic head pulleys remove tramp iron from the ore, the former to remove iron near the surface and the magnetic pulley for tramp iron close to the belt. Grinding Hematite Ore. Increased efficiency of grinding is obtained by using two stage grinding.

STRATEGIES FOR PROCESSING LOW-GRADE IRON ORE MINERALS .

For example, many ores contain iron oxide in a nonmagnetic form and are so fine-grained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue. Exploitation of these iron minerals needs to take a different approach, using fewer process steps than are required for conventional ironmaking.
