Flotation Behavior Difference between the Pure Quartz and the Quartz Gangue of a Siliceous-Calcareous Phosphate Ore with Fine Size

Abstract:

Flotation behavior of pure quartz is difference from that of the quartz gangue of a siliceous-calcareous phosphate ore with fine size. The flotation of pure quartz can attain satisfactory results at alkaline conditions. The IR analysis shows that adsorption intensity of quaternary ammonium salt is stronger which is likely to explain its preferable flotation performance for pure quartz. However, for quartz gangue of phosphate ore, the results are completely opposite. The acid condition is more favorable for reverse flotation than alkaline condition due to the existence of carbonate mineral. The alkyl amine salt is a more effective collector to remove quartz gangue from siliceous-calcareous phosphate ore, especial with 12 carbon chain. Zeta potential of the ore treated by it is almost higher than that by the other alkyl amine salts (with 10, 14 or 18 carbon chain), which suggests its stronger absorption on ore particles.
