This paper proposes a new technique for the actuation of spiral units that is suitable for large-scale retrofitting on industrial spiral circuits. Test measurement data from an industrial mineral sands spiral plant in South Africa is presented in order to quantify the extent of the mineral band variation on the surface of the spiral.

Gravity separation is a important mineral recovery method and has been the main beneficiation sector used in gold mining plants, alternatively ahead of other processes such as flotation and cyanidation. Gravity separation is an environmentally friendly beneficiation method that relies on water flow and gravity to separate target value minerals and gangues.
