THE EFFECT OF VARIOUS PARAMETERS IN THE SELECTIVE FLOTATION OF BITLIS MUTKI COPPER ORE

In this study, the effect of various flotation parameters on the selective flotation of a sulfide copper ore belonging to the Bitlis Mutki region was investigated. The ore sample contains chalcopyrite, pyrite, pentlandite as recoverable precious mineral, pyrrhotite, millerite, galena, sphalerite, bornite, chalcosine, covelline as trace amount, amphibole, mica, pyroxene, feldspar, talc, calcite, serpentine, olivine, quartz, chromite as gangue mineral. According to the results of chemical analysis, the ore sample contains 0.81% Cu, 9.19% Fe, 2.89% S, 3 g/t Ag, 0.39 g/t Au, 0.12% Ni, 0.71 g/t Pt, 2.28 g/t Pd. The effects of flotation parameters such as particle size, rotor speed, amount of collector, and type of frother on the recovery of valuable elements (Cu, Ag, Au, Ni, Pt, Pd) in the ore were investigated. Cu was recovered with 3.82% grade and 91% yield from the rough copper concentrate obtained as a result of the flotation studies. In the rough copper concentrate Ag with 8.03 g/t grade and 57.5% yield, Au with 0.92 g/t grade and 43.1% yield, Ni with 0.49% grade and 55.8% yield, Pt with 3.39 g/t grade and 69.62% yield, Pd with 9.71 g/t grade and 67% yield was recovered. In the coarse concentrates obtained, two-stage cleaning was performed for chalcopyrite, and one-stage cleaning was performed for pyrite, and the desired result was achieved a copper concentrate with 14.26% grade and 80.9% recovery After cleaning circuits.
