Aug 01, 2016 · For the porphyry copper ore tested in these investigations, a coarse copper sulphide grain size coupled with a high association with hard microwave-transparent (i.e. quartz) and hard microwave-heating (i.e. pyrite) minerals resulted in a grind size increase of 50–60 μm for equivalent liberation or an approximate 2.5% increase in liberation at an equivalent grind size.

AEROPHINE Ⓡ promoters, such as AEROPHINE Ⓡ 3421 and AEROPHINE Ⓡ 3422, can be used as the primary collector in flotation of porphyry copper ores that contain significant amounts of gold and silver. These promoters are highly effective in the recovery of coarse middlings and can therefore be used even at coarse grind.
