【摘要】 通过矿物表面糊精吸附量的测定、电动电位测定及在不同ｐＨ值下矿物表面羟基浓度的测定，系统探索了糊精在赤铁矿、金红石、方解石、萤石、重晶石、磷灰石及硅灰石等氧化矿和盐类矿物表面附吸的规律，发现糊精的吸附主要是由于与矿物表面金属羟基化合物发生了程度不同的化学作用。更多还原

【Abstract】 A study has been carried out to investigate the adsorption behaviour of dextrin on the surfaces of oxide the salt-type minerals such as hematite,rutile,calcite, fluorite, barite, apatite and wollastanite by means of adsorption isotherm and electrokinetic mobility memasurements,as well as mineral surface hydroxyl group concentration determinations. It is found that the adsorption of dextrin on the tested minerals is achieved through interaction with surface metal hydroxy complexes of the minerals.更多还原
