Electrostatic Separator

Electrostatic High-Tension Roll Separator (HTR400)

The Mineral Technologies Carrara HTR 400 offers the most advanced electrostatic separator on the market. The 400mm diameter roll along with the electrode design delivers separation efficiencies not previously seen. This affords the best opportunity for maximizing throughput, grade and recovery in plant operations. With some feedstock’s a two stage Carrara HTR 400 offers superior performance to 3 stage machines currently on the market. 

Elecrostatic Plate Separator

Electrostatic plate separators are used to separate dry, free flowing materials with particle sizes between 40 and 800 microns that exhibit differences in surface electrical conductivity. The unit is most efficient at removing finder sized conductors from coarser sized non-conductor materials. 

Separation of dry granular materials with differing electrical conductivities, eg:mineral sands, hard rock ilmenite and rutile, cassiterite, tantalite, wolframite, iron ore

Separation of plastics from metals in waste recycling systems and PVC from other plastics

Removal of contaminants from most granular, free flowing feedstocks 

MD Spirals

Designed and manufactured by Mineral Technologies, MD Spirals is a gravity beneficiation equipment that has proven its success in the separation of fine grain size minerals.
