Abstract
Copper ore from the Veliki Krivelj (RTB Bor, Serbia) is a porphyry type, main mineral of copper is chalcopyrite.
The most important accompanying mineral is pyrite, content in the ore is about 10%.
In a sample of ore from the mine Veliki Krivelj it was carried out research with the aim to determine the optimal
reagent regime. Experiments were carried out with the available flotation reagents, the goal is to determine the
influence of each collector on copper recovery and to determine the optimal combination of collectors also the
optimum dose of the collector. Reagents applied in the study are IPETC, PEX, SIPX, MBT (Isopropyl ethyl
thionocarbamate, Potassium ethyl xanthate, Sodium isopropyl xanthate, Mercaptobenzothiazole). In the following
studies were carried out experiments to determine the effect of fineness of grind on the recovery of copper.
The results indicate that is the biggest copper recovery using a combination IPETS and PEX also the results show
that the copper recovery directly proportional to grinding fineness.
