利用不同乳化剂与油酸进行复配改性，以提高普通油酸的低温适应性。以辽宁某地的长石矿为试验原料，对低温下长石与方解石浮选分离进行研究，并对改性油酸与方解石的作用机理进行探讨。结果表明，改性油酸能有效地提高低温环境下长石浮选提纯的指标，获得CaO含量小于0．3％，去除率达85．67％的长石精矿。动电位与红外光谱测试表明，复配油酸在方解石上的吸附量大于长石，且吸附形式为化学吸附。

Oleic acid was compounded and modified by utilizing different emulsifiers in order to enhance its flotation performance at a low temperature .The feldspar ore from Liaoning was taken as the experimental samples to explore the separation condition of feldspar and calcite at a low temperature ,and to discuss the action mechanism between modified oleic acid and calcite in flotation .The results showed that modified oleic acid effectively improved the quality of feldspar concentrate by flotation at a low temperature ,and the content of CaO of the concentrate was under 0 .3% and the removal rate was 85 .67% .The tests of zeta potential and FT‐IR demonstrated that modified oleic acid adsorption on the surface of calcite was higher than that of feldspar ,and the type of adsorption was chemisorption .
