Flotation upgrade at Nui Phao Outotec

Sep 21, 2017· SkimAir Flash flotation cell. Flash flotation (SkimAir SK500) was also investigated by Outotec as part of the BSF upgrade. The objective was to increase the recovery of liberated coarse (+106 μm) sulphur minerals and lower the BSF tails further from <2.5% S to 1.5% S. The justification for flash over conventional flotation was based on the
