Jigging
A gravity separation method that sorts particles by density in a pulsating bed of water.
In a jig, crushed ore sits on a screen while water pulses up and down through it. Denser particles, such as barite, settle to the bottom while lighter waste rock moves to the top and is removed.
For barite, crushing, screening and jigging can produce a high-grade concentrate of over 80%. Separate jigs are often used for coarse and fine fractions.
