This paper presents part of a complex technological flotation investigations of copper ore from the upper layers deposit "Veliki Krivelj". Ore copper content is in the average range and sulfur content is significantly higher than usual. High content of sulfur derives from the increased content of mineral pyrite, which is very difficult to depress in flotation. Because of this, it is very difficult to control and to stabilize flotation process and technological results are below the planed one. In order to increase the flotation process efficiency and the copper concentrate quality, technological laboratory tests were conducted in the ITNMS Mineral Processing laboratory. Investigations were undertaken with an aim to examine the possibility of applying new collector structures (manuf. Flomin) which are implemented effectively for the ores with similar features in the World. The results in paper presents technological effects achieved by applying the tested collector and compared to the r...eagent that is used in the Flotation Plant "Veliki Krivelj ". Because of the good results, which showed that the tested collector has a high selectivity for copper, it was decided to be tested on an industrial scale.
