FIELD: process engineering.
SUBSTANCE: invention relates to mining, particularly, to dressing of minerals, e.g. ores of ferrous, nonferrous and noble metals, nonmetallic minerals and man-made formations. Proposed method comprises crushing, shredding, sizing and drying of mineral processing products before electric separation. Drying is carried out at natural positive temperature of processing product and decreased pressure of 1-150 mm Hg. Heat power released in phase transfer is returned to drying process.
EFFECT: higher environmental safety, power savings.
