Flotation results using a single mineral and real ore showed that PbBHANaOL had better selectivity for scheelite than PbBHA When Pb BHA and NaOL were sequentially assembled in a 2401201 molar ratio at pH 90 the selective separation of scheelite from fluorite was successfully achieved without adding depressants The floatation of scheelite is under the room temperature and the product in tank is calcspar fluorite The Separation of Scheelite and Barite It is difficult to separate scheelite and barite by sodium silicate because of the closed inhibitory action for scheelite and barite We choose alkyl sulfate as collector to repeatly select barite
