Designed around a unique magnetic system with high capacity matrix material

Designed around a unique magnetic system with high capacity matrix material which together produces the required high magnetic field gradient to enable the capture of normally weakly magnetic or paramagnetic minerals
The unique magnetic system and design of the Metso HGMS very large unit capacities can be provided
The HGMS separators are available in several sizes and magnetic ratings to suit each individual application

The HGMS high gradient magnetic separator has a robust and simple design (few moving parts)
High magnetic fields and field gradients gives a good ”polishing” of contaminated products
Magnetic field from 3-20 kGauss and canister dia. up to 305 cm (120”)
The HGMS process system is compact designed and have fail-safe protection (thermal)
Completely automatic process control and customer built power supply

Process description
The separator handles particle sizes from 0,1 µm up to 1 mm and due to the excellent control parameters the metallurgical performance is superior. The cyclic HGMS is best suited for material with up to about 5 % magnetic matter in the feed. With no moving parts except for actuated valves handling controlled slurry velocities the maintenance cost is extremely low. Metso HGMS separators are able to remove even weakly paramagnetic materials.

Applications:Increasing the brightness of kaolin clay, reduction of copper in molybdenum concentrates, separation of chalcopyrite from Galena and Molydenium concentrate, reduction of Fe in glass sands, barites and ceramic clays, purification of coal, refractory materials and phosphates
