Introduction to Mineral Processing or Beneficiation

Grinding, the final stage used in the comminution process, is usually conducted in cylindrical tumbling mills where the particle size is reduced through a combination of impact and abrasion. The primary differences between these mills are in the ratio of diameter to the length of the cylinder and the type of grinding media employed.

Comminution tests aim to measure the comminution properties of ore samples to be used in designing and sizing the grinding circuit and to study the variation within an ore body. In the geometallurgy context this information is essential for creating a proper resource model for production planning and management and process control of the ...

General Processing Technology For Minerals | ST Equipment ...

In mineral processing, comminution uses the most energy, though originally it was even more labor-intensive. Centuries ago, small hand-operated pestles and mortars were used for crushing, and millstones, operated by men, horses, or waterpower were used for grinding. Today mechanized crushers and mills have greatly sped up this process.
