据统计,世界铜产量的20%以上是用溶浸技术生产的,且矿业界对溶浸采矿技术的关注度仍在持续增加。本期策划详细评述了采矿和浸出作业必须重视的关键工程--垫衬系统的防渗漏性能改进问题,指出在金属价格高企和环保法规日趋严格的当今时代,矿山运营者必须提高用于堆浸坝和浸液池底座的衬垫技术含量和质量,降低坝、池底部的溶液漏泄量,并延长衬垫的使用寿命。重点介绍了新型溶浸采矿技术之一--原地浸出,指出这种工艺是一种更具可持续性和环境友好性的方法,因为其具有投资少、运营成本低、无需在地表堆存矿石和废石等许多优点;文章同时详细介绍了应用原地浸出技术生产阴极铜的3个在建项目。
According to statistics, more than 20% of the world’s copper output is produced by the leaching technology, and the mining industry’s attention to the leaching mining technology continues to increase. This issue details in detail the key projects that must be taken into account in mining and leaching operations - the improvement of the anti-seepage performance of the liner system, pointing out that in today’s era of high metal prices and increasingly stringent environmental regulations, mine operators must increase their use of materials Baptist dam and immersion tank base cushion technology and quality, reduce the dam, pool bottom of the solution leakage, and extend the service life of the liner. Highlights one of the new leaching mining technologies - in-situ leaching, which states that this process is a more sustainable and environmentally friendly method because of its low investment, low operating costs and no need to stockpile on the surface Ore and waste rock and many other advantages; the article also details the application of in situ leaching technology to produce cathode copper 3 under construction projects.
