Novel gravity separation technologies extend to particle sizes of 0.01 mm. • These give new gravity concentration, classification and desliming opportunities. • There is potential to harness new synergies to redesign and simplify circuits. • A broad "question everything" approach is needed to see the above opportunities.

(2) Gravity-flotation-magnetic separation combined method According to the density difference between spodumene and gangue ore, the coarser particle size lithium ore is sorted first. When the density difference between spodumene and gangue is greater than 0.2-0.5g/cm3, it is suitable to use a shaking table or jig concentrator for separation.

For example, some flotation tailings and barite-fluorite associated ore can be recovered by gravity separation. The available machines are jigs, shaking tables, and spiral chutes.
