Experimental Study On New Floatation Process Of A Copper Ore In Jiangxi Province

With the development of the national economy, the consumption of copper in daily life is increasing. However, compared to other countries, China’s per capita reserves of copper resources is tiny, and the huge demand for the domestic copper resources make the problem even worse, and therefore, how to improve the utilization of mineral resources recycling is becoming increasingly important. Therefore, strengthen the comprehensive utilization of mineral resources, improve the utilization of mineral resources, have great significance on the long-term economic development of the country.The main subject of study is to get a property way to improve recovery and concentrate grade of a high-sulfur copper mine in Jiangxi province. On account of the existing floatation process, attempt to make full use of existing equipment, by improving the flotation process, optimize grinding and classification process, in order to achieve the purpose of improving the flotation index.The main contents of the paper:A detailed analysis of the ore properties, with using XRF, the polarizing microscope and MLA systems to have a deep understanding of the mineral composition, particle size characteristics and disseminated detailed analysis. Test ore samples belongs to the high-sulfur refractory copper ores associated with a variety of useful elements, The main ingredient of the mineral are chalcopyrite, pyrite, sphalerite, chalcopyrite. The chalcopyrite’ dissemination size is partial thin, and have a complex disseminated relationship. Based on the understanding of the ore properties and the analysis of the existing on-site production practices, start small-scale test toward the ore samples, and analysis of the problems existing in the original process, then attempt to indentify the problem which existed in the original process toward the detailed analysis of the original process, on this basis to improve the process of closed-circuit test. The new improved process to obtain ideal separation indexes closed-circuit test indicators of the new technology than the original process, copper concentrate grade increased by3.050%and copper recovery increased by1.23%. In a word, the new technology have a more ideal closed-circuit test indicator. After the small-scale test is completed, we attempt to transform existing processes of the concentrator on combination of the existing devices in the concentrator, and start industrial test of the new process, Industrial test results show that the new process compared with the original process copper recovery increased to1.02%copper grade increased by2.017%. Indicators have obvious advantages.On the basis of research and analysis in industrial test of the new process and the original process, we investigate in detail and compare the new floatation flow towards the original process, by the sieve analysis polarizing microscope identification and determination of the degree of dissociation, make a detailed analysis of the mine in the new process and the original process, New processes have effectively solved the problem of quickly concentrator tailings in the original process, increased the concentration of re-grinding operation, and beneficial to improve the regrinding efficiency to get the greatest degree of dissociation, new processes regrinding overflow chalcopyrite dissociation degree reached82.37%. A better solution to the problems that exist in the original process. Using infrared spectroscopy analysis copper collector OP and chalcopyrite surface adsorption. Verify that the lipid Pharmacy for priority copper process feasibility.
