摘要

FIELD: process engineering.
SUBSTANCE: invention relates to ore dressing and may be used for processing oxide nickel ore to up performances in pyrometallurgical production of ferroalloys. Proposed method comprises grinding ore to 2.0-3.0-mm-size, thermal treatment of ground ore to 550-600°C for, at least one hour, magnetic separation of annealed ore to extract magnetic fraction, fractionation of nonmagnetic fraction in its upward flow at hydrodynamic conditions and flow speed of 30-50 m/h to extract fraction of minus 0.3 mm.
EFFECT: power and material savings, simplified process.
