LINE FOR CONCENTRATION OF OXIDISED NICKEL-BEARING ORE Russian patent published in 2009 - IPC B03B7/00 C22B23/00 

FIELD: mining engineering.

SUBSTANCE: invention relates to gravitational concentration field, particularly to equipment for processing of mineral raw materials, and can be used for concentration of oxidised nickel-bearing ore. Line for concentration of oxidised nickel-bearing ore includes unit for concentration, consisting of installed by process device for grinding and repulping in the form of dibhole with hydraulic monitor, device for additional grinding and washing in the form of disintegrator with elastic lamellar diaphragm for formation of cavitational effect, at least of one hydraulic cyclone for separation of sinking fraction by density, connected to deviece for separation in the form of conical separator, at least two devices for cleaning of sinking fraction, located after the device for separation, device for cleaning of floating fractions, connected to disintegrator, hydraulic cyclone and conical separator, and lapping unit of concentrators, consisting of at least two devices for drying and two devices for separation. Line additionally includes device for thickening, located between hydraulic cyclone and conical separator. In the capacity of devices for separation of lapping unit there are used electrostatic and/or magnetic separators.

EFFECT: effectiveness increase of processing of oxidised nickel-bearing ore and receiving of desired product with higher content of nickel.
