| Description
| - The mineral deposit Bor-Cerovo is a relatively simple Cu-(Fe)ore that is becoming poorer and more complex in texture with the depth of mining. The Bor Copper Mine has expanded mine workings to the Cerovo field margins, where the same type of porphyry copper ore was found for which the Bor Mine is known as one of largest in Europe. Under the oxidized zone in the vertical deposit section lie paragenetic mineral associations typical of the cementated zone, or a transitional layer from the primary mineralized rock. Average concentrations of sulphide copper and oxide copper in the primary rock range from 0.263% to 0.164% and from 0.102% to 0.008%, respectively. Concentration of the ore of simple mineral composition has given a product of unsatisfactory both concentrate quality and metal recovery. More study is felt necessary of the structural/textural properties, of the identified mineral relations, and of the rate of mineral product liberation for the given grind fineness. Mineralogical analyses were conducted in the course of laboratory (and technological) tests. It has been learned that chemical analyses of the floatation concentrated material alone were inadequate, especially where complex texture of intergrowths and poor ore were involved. Structural properties and complex integrowths, and concequently low liberation degree, were found to be the reason of poor concentration. This paper discusses importance of the mineral liberation measurement for the technological results of copper ore concentration at the Bor-Cerovo flotation plant, and explains the functional relation between the mineral liberation and the grind fineness. Data on the microscopy of ore texture and the mineral liberation degree presented in this paper are aimed at improving the recovery and grade of chalcopyrite concentrate in the Veliki Krivelj Flotation Plant. Ore microscopy in the laboratory and technological tests indicate that chemical analysis as a tool for monitoring ore flotation ...
