Thefirst step of physical beneficiationis crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]). This type of flow sheet is usually followed when the crude ore contains below 30% iron.

One stage grading process with checking grading operation is the most widely used. The ore is directly fed into thegrindingmachine, and the optimum particle size for the ore is generally 6-20 mm. Particle checking classifier separates the ground material into qualified products and unqualified products, the unqualified materials are sent back togrindingmill.
This course covers thecrushing,grinding, and associated equipment to ensure adequate feeding, in quantity and quality, to the milling plant. There are two basic types of ballgrindingsystems: opencircuitand closedcircuit. In the opencircuitsystem, the mill product has the fineness required for the next stage of the process.
