A method for determining metal phase in natural and man-made ores includes selecting and drying a representative sample, reducing the sample by quartering, grinding the quartered dry sample, classification of the ground sample, reduction of a heavy fraction, analysis of obtained material. Grinding the quartered dry sample and classification of ground sample by pneumatic separation are performed jointly at application to the combined process of a centrifugal field in a vortex mode of ground particles movement. |
