Abstract
The experimental research into intensification of copper-nickel ore concentration by flotation and magnetic separation shows that pre-treatment of ore before milling by accelerated electrons results in the increased yield of - 0.071 mm size and in enhanced recovery of useful components in the concentrate. Magnetic separation improves complexity of use of mineral raw materials.
