Development of Technologies for the Flotation Processing of Copper and Precious Metal Ores with the Aim to Increase the Technological Results

In this project, optimization of technological parameters for processing the mineral resources, from Majdanpek, Veliki Krivelj, Cerovo and smelter slag, is planned. Characteristics of ore, metal content as well as physical-mechanical, structural-textural and mineralogical properties have changed in years so there is a need for adjusting the new optimal parameters. The need to re-determine the optimal fineness of grinding as well as other parameters of flotation process, such as pH value, reagent regime, etc. are of great importance. Also, final testing of the optimized parameters in the continuous semi-industrial flotation plant is planned. Industrial application of the project results would help to increase the recovery of metal, which makes the outcome of better financial effects and raising the competitiveness of enterprise. Program of the project is also planning development of laboratory prototype for smelter slag granulator for experimental testing in order to decrease the resistance to comminuting. This can have an impact on reduction the normative and energy savings required for grinding. It is particularly important because the new system of smelting predicts that slag should be processed by the flotation process. Experiences indicate great problems in grinding of material, which is the subject of project research. Result is the suggestion the new technology for industrial deposition of slag. This would lead to the significant technological and economical effects.
