采用正阴离子混合捕收剂十二烷基胺（DDA）和油酸钠（NaOL）对白钨和方解石的浮选行为进行了研究。还检测了个体NaOL或DDA进行比较。采用DDA/NaOL混合捕收剂在pH 7条件下对方解石中白钨矿的浮选具有较高的选择性和回收率。通过zeta电位测定分析了选择性分离的吸附机理。(C) 2016 Elsevier Ltd.版权所有。
In this study, flotation behavior of scheelite and calcite was investigated using mixed cationic/anionic collectors of dodecylamine (DDA) and sodium oleate (NaOL). Individual NaOL or DDA was also tested for comparison. The flotation results of single mineral and mixed binary minerals demonstrated a high selectivity and recovery for the flotation of scheelite from calcite at pH 7 using mixed DDA/NaOL collectors. The adsorption mechanism of the selective separation was analyzed through zeta potential measurement. (C) 2016 Elsevier Ltd. All rights reserved.
