摘要

摘要: 浮选是回收钛铁矿的有效手段，其中捕收剂起着关键作用。目前对钛铁矿捕收剂的研究主要集中在以油酸、羟肟酸等为代表的捕收剂方面，其中苯甲羟肟酸类捕收剂以其高选择性备受关注，但其在对钛铁矿的浮选作用机理方面的研究甚少。从钛铁矿界面性质研究出发，通过单矿物浮选试验、红外光谱、接触角及动电位测定解释了苯甲羟肟酸与钛铁矿的浮选作用机理。

Abstract: Flotation is an effective means to recover ilmenite, in which collector plays a key role. At present, the research on ilmenite flotation collectors mainly focuses on the collectors including oleic acid and hydroxamic acid. Among them, benzohydroxamic acid based collectors have attracted much attention because of their high selectivity, however, there is little research on the flotation mechanism of ilmenite. Based on the study of the interface properties of ilmenite, the flotation mechanism of benzohydroxamic acid and ilmenite was revealed by means of single mineral flotation test, infrared spectroscopy, contact angle and potentiodynamic test.
