Separation
Gravity Separation Equipment
Gravity separation equipment recovers minerals based on density difference in a fluid medium. These units follow comminution and sizing stages in the flowsheet, and they produce a concentrate of higher-density valuable minerals while discarding lower-density gangue.
Equipment in this category
This page helps you choose among the main gravity separator types: concentrating tables, jigs, spiral chutes, and centrifugal concentrators. Your decision will depend on liberation size, feed density, throughput needs, and the recovery target for your specific orebody.
Concentrating tables handle finer feeds and produce high-grade concentrates. Jigs treat coarser particles with high unit throughput. Spiral chutes suit moderate size ranges at low cost per tonne. Centrifugal concentrators recover fine heavy minerals that would otherwise be lost. Each type has variants optimised for particular feed characteristics.

What decides the selection
Selecting a gravity circuit starts with laboratory testwork on your sample. Density difference and liberation size determine which gravity forces are effective. Feed density and water consumption are optimised during pilot trials. Throughput per unit area scales from batch tests, while stroke and frequency are set by the specific machine design and particle behaviour. The recovery target ties these choices to a measurable economic goal.
