AB  - The presented results refer to the investigation of effect the mechanical-chemical activation of flotation tailings on copper, iron and sulfur leaching degree in the sulfuric-chloride solution with the addition of H2O2 as oxidant. A sample of the Bor flotation tailings (BFT) from the old Bor flotation tailing dump consists of pyrite and tailings as the main components, and is activated in a dry process of the vibro mill with (BFT1) and without (BFT2) addition of NaOH as the chemical reagent. Using the dry magnetic separation in thee high-gradient magnetic separator Sala, the samples were separated into magnetic and non-magnetic fraction, BFT MF and BFT NMF, respectively. Leaching of various treated samples showed that the highest level of copper leaching (98.7 wt %), was obtained for BFJ2 MF sample while the leaching degree of Fe and S was higher in non-magnetic fractions, up to 92.46 wt % in BFT1 NMF sample for Fe and 80.62 wt % for S in BFT2 NMF sample.
AB  - Prikazani rezultati odnose se na ispitivanje uticaja mehano-hemijske aktivacije flotacijske jalovine na stepen izluženja bakra, gvožđa i sumpora u sumporno-hloridnom rastvoru uz dodatak H2O2 kao oksidansa. Uzorak borske flotacijske jalovine (BFJ) sa lokacije starog borskog flotacijskog jalovišta sadrži 23% pirita i 75,23% jalovine kao osnovne komponente, a aktiviran je suvim postupkom u vibro mlinu bez i sa dodatkom NaOH kao hemijskog reagensa, uzorci BFJ1 i BFJ2, respektivno. Suvom magnetnom separacijom u visokogradijentnom magnetnom separatoru 'Sala', uzorci su razdvojeni na magnetičnu i nemagnetičnu frakciju, BFJ MF i BFJ NMF, respektivno. Luženje različito tretiranih uzoraka pokazalo je da je najviši stepen izluženja bakra, 98,7 %, postignut kod uzorka BFJ2 MF dok je stepen izluženja Fe i S viši kod nemagnetičnih frakcija, i kreće se do 92,46 % kod uzorka BFJ1 NMF za Fe i 80,62 % za S iz uzorka BFJ2 NMF.
