Abstract
One of the most common methods for enriching iron-containing minerals is the magnetic separation method. In this work, dry separation was carried out using a magnetic separator for weakly magnetic ores. A sample of a mixture of coal preparation waste from JSC Central Processing Plant “Berezovskaya” BF-4, BF-5 (rock from JSC Central Processing Plant “Berezovskaya”, urban-type settlement Berezovsky, Kuzbass) was studied. Tests were carried out at different current strengths: 5 A, 10 A, 15 A. Based on the results of the studies, it was concluded that the recommended mode, according to the results of X-ray fluorescence analysis, is the grinding of coal enrichment waste to a size of 0,032 mm, followed by magnetic separation at a current strength of 5A; further increasing the current strength is impractical, since it will entail the extraction of associated unwanted gangue impurities.
