The development of regrind-flotation pre-treatment

However, copper minerals unrecovered by the flotation process are also present in the CIL feed and, similar to gold, these copper minerals are also encapsulated by the rejected iron sulphide minerals. In the case study previously reported by Burns et al. (2014) on Telfer gold mine’s CIL circuit, the use of an ultra-fine grinding pre

In 1991 the introduction of a Netzsch laboratory stirred mill to the Mount Isa site was a turning point in fine-grinding and ultrafine grinding. The litre bench scale mill resembled a milk shake maker and used fine copper smelter slag as grinding media. Testwork on McArthur River ore started in 1991, and by January 1992, a small pilot scale
