摘要
本文通过试验研究了萤石、重晶石和方解石的可浮性与捕收剂油酸用量及 pH值的关系。试验发现浮选萤石、重晶石、方解石所需要的油酸用量不同 ,次序为 :萤石 <重晶石 <方解石。萤石和重晶石在pH为中性左右时可浮性最好 ,而方解石在强碱性条件下可浮性最好。本文还通过矿物表面电性状态等探讨了油酸捕收萤石、重晶石和方解石的作用机理。
The relation of the flotation behaviors of fluorite,barite and calcite,with pH value and oleic acid concentrations has been studied by flotation measurements.The minimum oleic acid concentrations required for maximum flotation responses of fluorite,barite and calcite differ widely,as below,fluorite <barite<calcite.It is found that the maximum flotation response for fluorite and barite occurs at about the mid pH region;while the maximum flotation response for calcite is obtained at high pH region.The possible mechanism of collector oleic acid absorption is discussed.
