摘要

摘要:在更高的净产量(或更小的工厂占地面积)下,排矸石会导致原矿品位增加,并为替代加工流产生双重产品,如高品位和低品位,这是正在研究的两种处理方案,目的是将原本不经济的矿石转化为储量。目前,已经使用排矸适应性试验(GRAT)评估了11种金矿石通过重力分离排矸的潜力。这些样品代表了来自几个大陆和黄金生产商的各种金矿类型。此外,还使用四种不同的破碎模式对两种矿石进行了处理,以表征破碎类型对释放的影响。得到的GRAT数据库可用于基准测试,并确定每种矿石的最佳黄金损失与质量拒绝响应,给定元素迁移的影响作为基于尺寸和密度的分离的函数。

Gangue rejection responses for a variety of gold ores
ABSTRACT Gangue rejection, resulting in an increased head grade at a higher net throughput (or, smaller plant footprint), and the creation of dual products, eg high grade and low grade, for alternative processing streams are two treatment options being investigated to turn otherwise uneconomic ores into reserves. Eleven gold ores have now been assessed for their potential for rejection of gangue by gravity separation using the gangue rejection amenability test (GRAT). The samples represent a variety of gold ore types, from several continents and gold producers. Additionally, two ores have been processed using four different crushing modes to characterise the influence of crush-type on liberation. The resulting GRAT database can be used for benchmarking and to determine the optimal gold loss vs mass rejected response for each ore given the influence of elemental deportment as a function of size and density based separation.
