title = "Beneficiation of haematite from fluorspar tailings by reverse flotation",
abstract = "Fluorspar tailings produced at Vergenoeg Mine contain a substantial amount of haematite. Reverse flotation of haematite from the tailings has been investigated using a batch, bench-scale mechanical cell. Characterisation of the fluorspar tailings was done and effects of various operating parameters on the recovery of haematite were studied. The results showed that 80% of the tailings particles were-150μm in size and major mineral phases are haematite, quartz and calcium tecto-dialuminodisilicate. It contains 69.4% haematite. Dodecylamine (DDA) is a better collector than Betacol and a highest grade of 60.8%Fe was achieved using 300g/t DDA, 400-600g/t starch as depressant and at a pH of 8. Si content in the sinks was reduced to 2.83%.",
