磷酸盐分离胶磷矿和白云石的作用机理

The Mechanism of Separation of Francolite and Dolomite with Phosphates as Depressants

通过浮选、红外光谱和Ｘ光电子能谱，研究了油酸盐在白云石和胶磷矿上的吸附情况，较好地解释了在焦磷酸作用下，白云石仍保持其可浮性的原因．

The results of flotation test and the measurement with FTIR and XPS show that sodium oleate is adsorpted on dolomite and Francolite. It explains the reason that dolomite is easily raised than Francolite after adding pyroaphosphoric acid.
