通过单矿物浮选试验、吸附密度试验、Zeta电位测定、溶液化学分析和FTIR分析，研究了Fe3+对油酸钠浮选锆石和锡石的影响。单靠NaOL很难分离出锆石和锡石。Fe3+对锆石的浮选有激活作用，而对锡石的浮选有抑制作用。吸附密度测试表明，Fe3+的加入使NaOL在锆石表面的吸附增强，而在锡石表面的吸附减弱。Zeta电位测量和溶液化学分析发现，H(OL)(2)是决定锆石和锡石浮选行为的主要物种。此外，Fe3+在pH值下的添加
The effect of ferric ions (Fe3+) on the flotation of zircon and cassiterite using sodium oleate (NaOL) was investigated by single mineral flotation tests, adsorption density tests, zeta potential measurements, solution chemistry analyses, and FTIR analyses. It is difficult for zircon to be separated from cassiterite by using NaOL alone. Nevertheless, the flotation of zircon was activated while that of cassiterite was depressed in the presence of Fe3+. Adsorption density tests indicated that the addition of Fe3+ enhanced the adsorption of NaOL on zircon surfaces, whereas it receded on cassiterite surfaces. Zeta potential measurements and solution chemistry analyses found that H(OL)(2) was the predominant species to determine the flotation behaviors of zircon and cassiterite. Furthermore, the addition of Fe3+ at pH
