. 2 associated with the development and utilization of resources of all of sulfur mine sulfur mineral recovery processes, most of the use of flotation of copper, copper mine tailings of sulfur re-election process. Inhibited by the alkalinity of the sulfur, and the flotation concentration of low sulfur re-election when the flotation of pyrite is difficult, resulting in lower sulfur recovery. Through experimental research, using flotation concentrate after dehydration with acid or acidic wastewater decreased pH, increased flotation concentration, teach good fruit. If Wushan Copper Mine increased sulfur recovery rate from 35.84% to 52.8%; Yongping copper mine for ore properties, change the bulk flotation process priority for the bulk flotation process step by step to increase the selection of sulfur acid flotation time and added DH of water reduces the value of the sulfur recovery rate from 71.28% up to 8I. 86%,stivali ugg, the economic benefit of nearly 500 million. In addition, associated Dexing Copper comprehensive recovery of molybdenum and low-grade ores, oxide ores by heap leaching the West to take an electrical product of a reform process and the Tailings Recovery of Copper recover useful elements, are also achieved remarkable results. 3 Strategies for future development of the supply and demand of copper in China has been quite prominent, and consumption more than production. To a large extent reasonably taken to recovery of mineral resources, the need to improve the comprehensive utilization of mineral resources, mineral resources to carry out a comprehensive recycling efforts, to extend mine life and increase overall efficiency by squeezing, 3.1 to geological exploration work in the copper into mining, the use of geological analogy section metallogenic model, from known to unknown, research geological conditions surrounding the mine, continue to explore the deep side thoroughly, and to increase the reserves of mineral prospecting,ugg italia, effective way to expand the vision. Copper producing mines should strengthen the research on the deposit law to find the deposit accumulation and ore mineralization favorable areas, the discovery of new ore bodies and the search for new minerals. Associated components of the ore for geological investigation should be promptly determine and make survey work in order to master the components of the occurrence of associated characteristics, beneficiation process to develop a reasonable, comprehensive recycling, to become more of a ore mine. 3.2 The scientific and technological progress to accelerate scientific and technological achievements into productive forces, advanced technology is the vitality of mineral development. In the \progress, so that scientific and technological achievements into productive forces. Jiangxi Copper Company for 20 years to get over 300 major scientific and technological achievements, of which more than 121 provincial and ministerial level scientific and technological progress to obtain awards, but some still have not applied to production. If the company selected the sulfur recovery rate difference between the larger mines,air jordans, up to 8l%, the lowest less than 20% to 35% if the annual increase pyrite mine can be 40 million t, visible benefits are significant. 3.3 The emphasis on new product development research and improve the comprehensive utilization rate of technological innovation platform is the driving force to improve the comprehensive utilization of resources, technological innovation is market-oriented economic environment in the market, comprehensive utilization of resources, development of new products is a very important work, should increase the development and utilization of mine tailings, good secondary resources, comprehensive utilization of waste to treasure. Mining tailings without cost, without grinding, and can reduce the new tailings land, reduce environmental pollution is the main target of new product development. Tailings should also further strengthen the development of non-metallic products, such as Yinshan mine sericite, garnet Yongping copper mine development. 3.4 continue to apply for a heap leach extraction electrowinning process for a recovery of low crystalline bits of copper ore at present, many of our resources are exhausted at the edge of copper, the new replacement proved a serious shortage of reserves, therefore, make full use of existing secondary resources is of great significance. According to a foreign heap leach extraction-electrowinning technology a trend,ugg stivali, combined with supply and demand of copper production, the future recovery by heap leaching of low grade copper ore, is a relief to not work. Jiangxi Copper Company owned the mine in recent years has gradually built a scale ranging from heap leaching plant, accumulated rich experience. Practice has proved that, using heap leaching, solvent extraction, electrowinning recovery process low-grade copper ore, low cost, simple process, low material consumption, investment, short construction period and so on. Both the full use of limited natural resources, while protecting the environment. Therefore, leaders at all levels should arouse enough attention to mining, strengthen management and realize the diversification of resource development, resource development to improve the overall results. 3.5 to speed up development and construction of new projects is a large gate Copper sulfur deposits of copper, one of preparation has been done during the preparatory work and scientific research, including surface water and groundwater management, free of copper oxide mineral recovery, high zinc copper-zinc separation test,ed hardy, draw \Has started to do preparatory work for a large mine development, the advantages of resources to play as soon as possible.
