This 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 combination of the allflux
·1 Introduction The processing of heavy minerals and coal is often carried out using spiral classifiers Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral such as quartz is carried out in circuits with several hundreds of rougher cleaner and re cleaner spirals Bazin et al 2014 The development of spiral circuit
·Reverse flotation process was optimized by an experimental programme based on statistical analysis for reduction of silica and alumina levels from screw classifier overflow so as to enrich iron
It was found that a 63 per cent Fe product can be produced from a single stage using the Optima Classifier® Fine iron ore feed with an average head grade of 50 per cent Fe was upgraded to average concentrate grades of per cent Fe Displaying upgrade ratios of up to in a single stage A three stage rougher cleaner and scavenger
The low grade clay rich mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming wet high intensity magnetic separation WHIMS spirals and final dewatering using fine screens Very fine < mm clay rich slimes simply
