view moreThis paper demonstrates the suitability of utilising the allflux two-stage fluidised bed classifiers to treat iron ore particles up to 2 mm in size as well as showing how the high capacity gaustec wet high intensity magnetic separation (WHIMS) technology offers several advantages compared to other WHIMS technology.The combination of the allflux ...
view moreThe recovery and concentration of ultra-fine iron ore can provide significant economic benefits. Presently, there are limited options available given the low settling rates achieved by conventional gravity separation and the relatively poor performance of reverse flotation. The Reflux Classifier is a new water-based gravity separation technology that consists of …
