Question

In size classification of ore particles, which equipment is commonly used?

• A. Rotary kiln
• B. Froth column
• C. Cyclone separator
• D. Ball mill

Hint:

Cyclone separators are your go-to devices for classifying ore particles by size using centrifugal force in mineral processing plants.

Answer 1

The Correct Option is C

A cyclone separator is a device used for classifying particles based on size and density using centrifugal force.
In mineral processing, it is commonly employed in the classification of fine ore particles. The separation occurs due to the difference in the inertia of particles in a spinning airflow, causing coarser or heavier particles to be thrown outward toward the wall, while finer particles exit from the center.
Rotary kilns are used for roasting, froth columns for flotation, and ball mills for grinding—not classification.
Therefore, the correct equipment for size classification is the cyclone separator.
