1ST STAGE-INDUSTRIAL TEST OF SEPARATING PARTIAL FLOW OF BAYAN OBO LOW AND MEDIUM GRADE IRON OXIDE ORES AND RARE EARTHS USING NEW TECHNOLOGY OF MAGNETIC SEPARATION AND FLOTATION SEPARATION

The results are presented of the 1st stage-industrial test of separating partial flow of Bayan Obo low and medium grade iron oxide ores to comprehensively recover iron and rare-earths using a process flowsheet consisting of low intensity magnetic separation, high intensity magnetic separation and flotation separation. The authors discuss its key techniques and analyse separating results of its main operations and separating behaviour of main minerals. It is concluded that efficient recovery of iron and rareearths can be achieved using the flowsheet.
