金属阳离子对盐类矿物浮选具有重要影响。通过浮选试验和动电位测试，研究了油酸钠浮选体系中五种金属阳离子（ Fe2＋、Fe3＋、Cu2＋、Ca2＋和Mg2＋）对常见碳酸盐矿物方解石和菱镁矿浮选行为的影响。动电位测试结果表明，五种金属离子都在方解石和菱镁矿表面发生了吸附，但其对方解石和菱镁矿浮选行为的影响不同：Fe2＋、Fe3＋对方解石和菱镁矿具有明显抑制作用，Cu2＋、Ca2＋和Mg2＋对菱镁矿有一定活化作用， Mg2＋抑制了方解石浮选，而Cu2＋和Ca2＋对方解石浮选影响较小。
金屬暘離子對鹽類礦物浮選具有重要影響。通過浮選試驗和動電位測試，研究瞭油痠鈉浮選體繫中五種金屬暘離子（ Fe2＋、Fe3＋、Cu2＋、Ca2＋和Mg2＋）對常見碳痠鹽礦物方解石和蔆鎂礦浮選行為的影響。動電位測試結果錶明，五種金屬離子都在方解石和蔆鎂礦錶麵髮生瞭吸附，但其對方解石和蔆鎂礦浮選行為的影響不同：Fe2＋、Fe3＋對方解石和蔆鎂礦具有明顯抑製作用，Cu2＋、Ca2＋和Mg2＋對蔆鎂礦有一定活化作用， Mg2＋抑製瞭方解石浮選，而Cu2＋和Ca2＋對方解石浮選影響較小。

Metal ions have significant effect on the flotation of salt minerals .In this study , the effect of five different metal ions on flotation behavior of two kinds of carbonate minerals , viz, calcite and magnesite was investigated by batch flotation tests and zeta potential measurement .Zeta potential re-sults showed the adsorption of all five metal ions on the surface of calcite and magnesite whereby the potential was observed to increase .But the results obtained by flotation tests showed that , the five metal ions had different effect on the flotation behavior of calcite and magnesite .Fe2+and Fe3+de-pressed calcite and magnesite flotation obviously .Recovery of magnesite was higher in the presence of Cu2+,Ca2+and Mg2+.Mg2+depressed calcite but Cu 2+,Ca2+had little influence on calcite flo-tation.
