摘要： 研究了在油酸钠浮选体系中菱镁矿、白云石和石英的浮游特性以及调整剂对3种矿物浮游性的影响，考察了白云石和石英对菱镁矿可浮性的影响，白云石对石英可浮性的影响以及白云石对菱镁矿和石英混合矿浮选的影响并研究了其机理.结果表明:在油酸钠浮选体系中，菱镁矿和白云石浮游性相近，六偏磷酸钠和水玻璃对菱镁矿和白云石的可浮性有一定的抑制作用；3种矿物会产生交互影响，白云石和石英会降低菱镁矿浮选回收率，而白云石会提高石英浮选回收率，其原因主要是由矿物罩盖和矿物溶解所引起的.

Abstract: In the floatation system with sodium oleate as collector， the floatability of magnesite， dolomite and quartz and the effects of regulators on floatabilitiy of those three minerals were studied. In addition，the influences of dolomite and quartz on the floatability of magnesite， the influence of dolomite on the floatability of quartz and the influence of dolomite on the floatability of the mixture of magnesite and quartz were researched， and their mechanisms were explored. The results show that taking sodium oleate as collector， the floatabilities of magnesite and dolomite are close，and sodium hexametaphosphate and sodium silicate can depress the floatability of magnesite and dolomite. Moreover， these three minerals have interactive effects each other. For example，adding dolomite or quartz can decline the magnesite recovery， and adding dolomite can improve the quartz recovery， which are basically caused by the dissolution of minerals and the coverage of minerals on each others.

Key words: magnesite, dolomite, quartz, sodium oleate, interactive effect
