| 摘 要： | 通过浮选实验及吸附量、麦面电性测定,研究了螯合剂与中性油对黑钨矿的捕收性能。中性油增加了螯合剂的捕收能力并降低其用量。中性油的作用是靠范氏力缔合于预先吸附在矿物表面的螯合剂非极性基上,增加了螯合剂在矿物表面的吸附量和其疏水能力。

| Abstract: | In this paper the collecting role of chelating agents combined with the neutral oils in wolframite flotation was studied using the methods of flotation tests and measurement of adsorption and zeta potential. The neutral oil increases the collecting ability of the chelating agent and decreases its dosages. The mechanism is that neutral oil molecule is physi- cally associated to the nonpolar group of the chelating agent pre-adsorbed on the mineral surface, resulting in an increase of the adsorption of the chelating agent on wolframite and its hydrophobic ability. |
