中文摘要：

研究了中低品位高效磷矿捕收剂ZM对胶磷矿和白云石浮选行为的影响，表面张力、润湿接触角、Zeta-电位测定结果表明：pH=8～9时，ZM能显著降低溶液的表面张力，有较好的表面活性；而pH=2．41～4．23时，ZM表面活性较低，不利于药剂分散。

英文摘要：

Study is made of the effect of middle-low grade phos- phate collector ZM on the flotation behavior of collophane and dolomite. The measurement of surface tension, wet contact angle and Zeta-potentials showed that when pH equals to 8-9, collec- tor ZM could significantly reduce the surface tension of solution and show better surface activity and when pH equals to 2.41 4.23, surface activity of collector ZM was low, which is not con- ducive to reagent dispersing.
