The Correct Option is C
Solution and Explanation
Concept:
Jigging is a gravity separation process used in mineral beneficiation.
It works on:
- pulsation of water
- stratification of particles
- difference in settling velocity
Step 1: Basis of separation.
Heavier particles settle faster: \[ v \propto \sqrt{\frac{\rho_p - \rho_f}{\rho_f}} \] So density difference governs separation.
Step 2: Evaluate options.
(A) surface chemistry → flotation (B) conductivity → electrostatic separation (C) specific gravity → correct (D) magnetic susceptibility → magnetic separation Final Answer: \[ \boxed{\text{Specific gravity}} \]
