| 摘 要： | 采用苯甲羟肟酸、C_(7～9)羟肟酸和油酸分别对钽铌矿、石英、长石三种纯矿物进行可浮性研究。结果表明:苯甲羟肟酸对钽铌矿有较强的选择捕收能力,在pH6.0～10.0范围内捕收效果最好,苯甲羟肟酸与辅助捕收剂WT_2以质量比3:1组合使用时,提高了分选指标,起到了“1+1>2”的协同效果。

| Abstract: | Benzyl hydroxamic acid, C_(7--9), hydroxamic acid, and fatty acid are used in the flota-
tion of columbite--tantlite, quartz, and feldspar, respectively. The test results show that
benzyl hydroxamic acid has good selectivity and great collecting power in the flotation of
columbite--tantlite at pH 6. 0--10. 0. When the compound of benzyl hydroxamic and WT_2,
mass ratio of which is three to one, is used in the flotation of columbite--tantlite, the separa-
tion index is raised, and a cooperation function of "1+1>2" is abtained. |
