halite spiral concentrator
foundations of theory and practice of minerallurgy
Fine particles are generated at the mines due to the mechanization and automation in the mining processes. Also, the occurrence of valuable minerals in a finely disseminated form necessitates fine grinding for liberation and subsequent physical separation.

Speed analysis of quartz and hematite particles in a spiral
Positron emission particle tracking was used to measure the speed of dense (hematite) and light (quartz) mineral particles flowing in the first two turns of a spiral concentrator. The analysis leads towards the following conclusions: the absolute speed of particles (size −1700 + 1180 μm) range from 0.04 to 0.55 m/s in the middle zone and 0. ...

Spiral Concentration
One spiral concentrator occupies about 0.37 m2 (4 ft2) of floor space and about 2.1 m (7 ft) of headroom measured from feed to discharge box. The optimum particle-size range of feed particles for spirals is about 10 to 200 mesh (2 to 0.074 mm). As the feed slurry flows down the spiral channel, the particles with the highest specific gravity ...
