摘要

由于白钨矿和方解石的表面性质相似，浮选分离困难。通过微浮选实验，研究了氧化石蜡皂(OPS)、苯甲羟肟酸(BHA)和OPS/BHA混合捕收剂对白钨矿和方解石的浮选行为。单矿物浮选实验结果表明，以水玻璃为抑制剂时，pH值为9的方解石中白钨矿的浮选选择性高于单独的OPS和BHA。为了验证研究结果的有效性，还成功地进行了混合二元矿物实验、接触角实验和zeta电位实验。

Flotation separation of scheelite from calcite using mixed collectors

Flotation separation of scheelite from calcite is difficult due to the similarities in their surface properties. In this work, the flotation behavior of scheelite and calcite using oxidized paraffin soap (OPS), benzohydroxamic acid (BHA) and the mixed OPS/BHA collectors was investigated through micro-flotation experiments. The flotation results of single mineral experiments demonstrated a higher selectivity for the flotation of scheelite from calcite at pH 9 than individual OPS and BHA when using water glass as depressant. In order to probe the validity of the findings, mixed binary minerals experiments, contact angle and zeta potential experiments were also carried out successfully.

期刊介绍： International Journal of Mineral Processing has been discontinued as of the end of 2017, due to the merger with Minerals Engineering. The International Journal of Mineral Processing covers aspects of the processing of mineral resources such as: Metallic and non-metallic ores, coals, and secondary resources. Topics dealt with include: Geometallurgy, comminution, sizing, classification (in air and water), gravity concentration, flotation, electric and magnetic separation, thickening, filtering, drying, and (bio)hydrometallurgy (when applied to low-grade raw materials), control and automation, waste treatment and disposal. In addition to research papers, the journal publishes review articles, technical notes, and letters to the editor..
