FIELD: mineral dressing. SUBSTANCE: method involves pulping of ore during 1 min, washing pulp in a wet medium to separate at least one fine fraction from grainy fraction using screen with mesh between 80 mcm and 3 mm so that grainy fraction contains no more than 10% fine fraction, after which grainy fraction is separated into middle and heavy fractions at separation density from 1.7 to 2.5 and light fraction is then recovered as concentrated ore. EFFECT: increased degree of removing oreless elements contaminating ore. 10 cl, 1 tbl, 7 ex
