植物油酸在白钨矿浮选中的捕收性能及差异分析（英文）
|
摘要
捕收剂的组成直接影响它在矿物浮选中的捕收性能。本研究采用三种植物油酸为捕收剂,通过浮选试验、动电位测试、接触角测量以及红外光谱测试考察了白钨矿的浮选性能及差异分析。浮选试验结果表明,白钨矿的回收率按照油酸<菜籽油<米糠油<大豆油的顺序递增,尤其是在pH=5～8之间。白钨矿浮选回收率的差异主要是由于这些捕收剂的组成不同而引起的。亚油酸、亚麻酸和十六酸(<5%)的添加能增加油酸对白钨矿的捕收能力,而十八酸的添加则恶化白钨矿浮选。动电位测试、接触角测量与红外光谱分析结果表明,当采用植物油酸为捕收剂时,捕收剂在白钨矿表面的吸附增强。对于含0.086%WO_3的原矿,采用大豆油为捕收剂,可以得到WO_3品位为1.423%,回收率为84.22%的白钨粗精矿。
The composition of a collector directly affects its collecting performance in mineral flotation. In this study,three vegetable oils were used as the collectors, the flotation performance of scheelite and the differential analysis were studied through flotation experiments, zeta potential, contact angle measurement and Fourier transform infrared spectrum(FTIR) analysis. Flotation results show that the recovery of scheelite increases in the order of oleic acid
