随着社会的发展,人们对铜的需要在不断地增长,可是矿山资源日趋贫化,因此对难选氧化铜矿石的研究与开发利用工作的现实意义越来越大。对我国几个主要产铜省价的不完全统计可知,氧化铜矿石中的铜金属量要占铜总储量的5—20％,个别省份占40％左右,所以对于这部份资源的开发与利用应予以充分重视。特别值得注意的是那些经过次生富集的矽卡岩型氧化铜矿床,它们的原矿含铜品位可达2—5％,其经济价值较高,然而这类矿石的可选性比较差,并且可选性与原矿中结合铜含量,矿泥含量成反比例,采用普通浮选工艺其结果是难以得到理想的技术指标,或者流程不畅通,操作不稳
With the development of society, people’s demand for copper is constantly increasing, but mine resources are getting depleted. Therefore, the research and development and utilization of refractory copper oxide ore are of increasing practical significance. On the incomplete statistics of several major copper-producing provinces in China, it is known that copper metal in copper oxide ore accounts for 5-20% of the total copper reserves and some provinces account for about 40%, so the development of this part of resources And use should be given full attention. Of particular note is the secondary enrichment of skarn-type copper oxide deposits, their ore grade copper content of up to 2-5%, its higher economic value, however, the selectivity of such ore is relatively poor , And the selectivity of the ore with the combined copper content, the amount of sludge is inversely proportional to the results of the ordinary flotation process is difficult to obtain the desired technical indicators, or the flow is not smooth, unstable operation
