| 简介 |
FIELD : mineral production, namely extraction of free metals (gold, platinum and others), oxides of many metals for separating electrically conducting particles and cleaning water.
SUBSTANCE : separator includes loading unit, means for moving flow of pulp, housing having ducts for individually discharging flows of separated components; unit for spatially dividing pulp flow by flows of separated components, said unit is in the form of magnetic system having electric current pulse generator and electromagnet. Electric current pulse generator may generate powerful current pulses at rate of increasing electric current in pulse dI(t)/dt no less than 108 A/s with asymmetrical in time form of electric current pulses having front edge duration less than that of back edge. Electromagnet is made with possibility of generating powerful impulse magnetic field with gradient (grad H) no less than 108 A/m2. Value of magnetic field intensity in duct for discharging flow containing useful component is equal to 0.
EFFECT : possibility for extracting fine and ultra-fine non-magnetic fractions of non-ferrous, rare and noble metals from mixture of dispersed non-magnetic materials.
