Coppermolybdenum ore beneficiation,flotation separation
In the coppersulfur separation operation, due to the large amount of lime and the fine grinding particle size, it has a greater impact on the corresponding flotation of molybdenite; in the actual copper separation operation, the copper recovery rate is only ≤50 % Classified slurry from the grinding circuit is dewatered in a flotation feed thickener from where feeds a three stage copper–lead–zinc sequential flotation circuit The copper flotation section produces a copper concentrate through two stages of flotation as shown in Fig 1 Flotation reagents are added through the conditioning tank, TKF2Flotation separation of copper sulphides from arsenic Flotation separation of copper and solder Flotation is commonly used to separate and recover minerals from gangue Here, flotation was used to separate copper from coppertin alloy Vibration mill was used in the fine crushing process of materialsNew insights into the mechanism of selective flotation of
