AN INTRODUCTION TO GRAVITY SEPARATION IN MINERAL PROCESSING Published on February 14, 2017 February 14, In simple processes (jigging, How Gravity Separation Works to Recover Metals and Minerals,This rudimentary piece of mineral processing equipment uses pulses of water to suspend the particles in water. As the pulses dissipate, the particles settle in the bottom of the jig. Particles with a higher specific gravity (like gold) settle faster than those with a lower specific gravity, effectively separating the gold so it can be collected.
