jigs for gravity concentration

A study of jig pulsation frequency in magnetite concentration

A jig plant is a gravity separator that uses pulsation (repeated expansion and contraction of a vertical bed of particles) of water. The result of this movement is the bed stratifiion, where the materials density splits in ascending order from the top to the bottom. Jig plant is used in the field of mineral processing and even metal recycling.
