Abstract

The paper presents the results of the latest tests of tailings from the old tailings in the Bor mine complex. A package of 31 elements was geochemically analyzed, in which with increased elemental contents are characterized the elements typical for the Bor ores such as copper (0.25–0.45% Cu), chromium (0.0047–0.1343% Cr), arsenic (0.0031–0.0127% As), selenium (0.30–4.77% Se), silver (0.15–2.87% Ag) and gold (0.08–0.65% Au). Miner- alogical study have shown the standardization of several minerals such as pyrite, bornite, chalcopyrite, magnetite and natural gold, which compositions have been confirmed by SEM–Scanning Electron Microscope. Quantitative mineral analysis gave the composition of the main constituents in the tailings dominated by quartz up to a maximum of 60.6%, amorphous mass up to 58.1%, ore minerals dominated by pyrite up to 20.4% followed by albite, microcline, hornblende and others.
