矿物表面的电性质,是影响浮选过程的重要因素,特别是一些氧化物其表面电性对浮选有着极为重要的作用。本试验研究,采用流动电位法测定矿物的ζ电位,该法具有精确度高,数据重复性好等优点。在测定ζ电位的基础上,确定了矿物表面重要参数零电点,据此可选用以静电吸引为基础的捕收剂。 The electrical properties of the mineral surface are important factors that affect the flotation process. In particular, the surface electrical properties of some oxides play a very important role in flotation. The test study, the use of mobile potential method to determine the ζ potential of minerals, the method has the advantages of high accuracy, good data repeatability. Based on the determination of zeta potential, the zero point of the important parameters of the mineral surface is determined, so electrostatic collectors can be selected.
