However for fine-grained ores there is no choice—clean concentrates can only be made from liberated particles. In some cases achieving liberation means grinding to sizes below 10 μm.For example, at Xstrata's McArthur River Mine (MRM), grinding to P80 of 7 μm is essential to produce a saleable concentrate.At Mt Isa, grinding streams to P80 …

1. Introduction. Froth flotation was undoubtedly the most innovative and groundbreaking discovery for mining in the 19th century (Wills and Finch, 2015).Nevertheless, it did not last long that scientists recognized its limitations for extremely fine and coarse particles, which has remained a long-standing unsolved issue in the …

"As a kind of non-metallic material, high-purify quartz sand has been widely used in many fields. Flotation is a popular way to process quartz sand. But it is in difficult position for flotation to get high-purify quartz product due to large amount of coarse particles contained in the feed. In this paper, a design principle of special flotation cell …
