Abstract: Directed at the properties of a molybdenum ore in Anhui,an experimental research on floatation technology was carried out.For its characteristics of uneven dissemination and being difficult to liberate,the technological flowsheet of Mo-S bulk flotation was adopted under the condition of the grinding fineness of-0.074mm75% and water glass used to depress the slime and gangue.Through the comparison of one-stage regrinding and five cleaning flotation with two-stage regrinding and five cleaning flotation,the re...
