《Minerals Engineering》2011年24卷11期发表Yousef Ghorbani等人文章,综述大粒度矿石对堆浸过程影响的研究结果。用堆浸技术可以经济地回收一些重要金属,如铜、金、银和铀。堆浸的特点是矿石的粒度比较大,对破碎或团粒矿石,最大粒度可达12～15mm,而对原矿石堆浸所用的矿石粒度可更大。对某些大粒度矿石的堆浸,通常可假设其过程遵循收缩核特性,尽管对这一假设的有效性还没有得到证实。作者对大粒度矿石的浸出特性和矿物学、大粒度矿石如何影响浸出特性以及用于表征这些特性的手段等方面的现状做了评述,包括矿石和粒度的特性研究、用于矿石表征的可视化技术、破矿尺寸与浸出性能之间的 Minerals Engineering 2011 Vol. 24, No. 11 Published Yousef Ghorbani et al., Summarizes the results of studies on the effect of large-size ores on heap leaching. Heap leaching technology can be economically recovered some of the important metals, such as copper, gold, silver and uranium. Heap leaching is characterized by relatively large particle size of the ore, the maximum particle size of crushed or pelletized ore up to 12 ~ 15mm, while ore ore heap leaching ore size can be greater. Heap leaching of some large-grained ores usually assumes that the process follows the properties of the contracting core, although the validity of this hypothesis has not yet been demonstrated. The authors commented on the current status of leaching characteristics and mineralogy of large-size ores, how large-sized ores affect leaching characteristics and the means used to characterize these properties, including characterization of ores and particle sizes, visualization techniques for ore characterization , Broken ore size and leaching performance between
