堆浸采矿技术源远流长,特别是最近几十年获得了广泛的工业应用。现在,堆浸不仅广泛用于世界各地的铜、金提取回收,而且也应用于从低品位的矿石资源中回收其他金属,如钒、锌、镍和钼等。当前,大型堆浸作业的关注焦点是影响环境和堆浸效果的矿堆底衬及垫衬系统、喷淋系统,以及矿堆渗透性的有关技术等。对于某些特殊矿种,如低品位钨矿物的浸出方法,科技工作者的研究重点是应用机械强化技术提高钨矿物的分解率和分解速率。“机械强化技术在钨矿物浸出中的应用”一文指出,边磨边浸的机械强化方式效果显著。难浸金矿石资源的开采处理技术一直是全球矿业界积极开展的研究课题,因世界上约30%的金资源属于难处理金矿。“难浸金矿石预处理工艺的研究现状分析”一文,评述了近年来国内外难浸金矿石预处理的工艺研究成果,并指明当前应尽快产业化的一些工艺技术。
Heap leaching mining technology has a long history, especially in recent decades has been widely used in industrial applications. Heap leaching is now not only widely used around the world for copper and gold extraction and recovery, but also for the recovery of other metals such as vanadium, zinc, nickel and molybdenum from low-grade ore resources. Currently, the focus of large-scale heap leaching operations is on the bottom lining and lining systems, sprinkler systems, and related technologies for the permeability of ore mines that affect the environment and heap leaching. For some special types of minerals, such as low-grade tungsten mineral leaching methods, scientists focus on the application of mechanical strengthening technology to improve the decomposition rate of tungsten minerals and decomposition rate. “The application of mechanical strengthening technology in the leaching of tungsten minerals ” article pointed out that the side edge of the mechanical strengthening mode immersion effect is significant. Exploitation of hard-to-leach gold ore resources has long been an active research topic in the global mining community as about 30% of the world’s gold resources are refractory gold. “Refractory gold ore pretreatment process research status analysis ” article, reviewed the domestic and foreign in recent years refractory gold ore pretreatment process research results, and indicate the current industrialization of some of the technology as soon as possible.
