The powdered ore is agitated with water or washed with running steam of water. The heavy ore particles and lighter impurities are separated. This method of concentration is known as

Options

  1. Ametallurgy
  2. Bleaching
  3. Cgravity separation
  4. Dfroth floatation process

Correct answer

C. gravity separation

Step-by-step solution

Gravity separation is based on the difference in the specific gravities of gangue and ore particles. In the stream of water, heavy ore particles settle down while the lighter gangue particles are washed away.
