摘要

摘要: 从钛铁矿界面性质研究出发，通过单矿物浮选试验、捕收剂吸附量、接触角及ζ电位测定，对比研究了油酸、苯甲羟肟酸对钛铁矿浮选作用的差异。认为油酸、苯甲羟肟酸在矿浆中均与钛铁矿表面发生了物理吸附和化学吸附，但主要以化学吸附为主。且苯甲羟肟酸对钛铁矿的浮选性能优于油酸，为新型钛铁矿捕收剂的研发奠定了理论基础。

Abstract: Starting from the study of interface properties of ilmenite, the single mineral flotation test, collector adsorption capacity, contact angle, and ζ potential measurement were conducted to study the mechanism of oleic acid and benzohydroxamic acid on the flotation of ilmenite. Oleic acid and benzohydroxamic acid underwent physical and chemical adsorption on the surface of ilmenite in the slurry, mainly through chemical adsorption. The difference in the flotation performance of oleic acid and benzohydroxamic acid on ilmenite was explained. Benzenehydroxamic acid shows better flotation performance for ilmenite than oleic acid, laying a theoretical foundation for the research and development of new ilmenite collectors.
