摘要
萤石与重晶石的浮选分离及药剂的作用机理研究结果表明,烷基α-羟基1.1双膦酸(TF28)是萤石和重晶石的优良捕收剂。以ND_(16)作抑制剂,可以实现萤石与重晶石的浮选分离。TF28在萤石、重晶石表面除存在化学吸附外,在重晶石表面还存在物理吸附。
The study of flotation and its mechanism indicates that the TF28 is a efficient collector for flourite and baritc. Separation of flourite from barite may be achieved by use of ND15 as a depressor. TF28 bonds chemically on the surface of both flourite and baritc and it also adsorbs physically on the surface of barite.
