利用由脂族醇硫酸酯改善的磺化琥珀酸盐捕收剂的混合物以及用有机酸和硅酸钠抑制杂质 ,直接浮选锡 ,从重选锡精矿中除去锆、钽和铌铁矿。利用这种方法可从锡重选精矿中除去90 %的杂质。锡精矿品位可从含 Sn O2 5 8%提高到 90 %。从钽、铌和锆中选择性浮选锡的主要影响因素是捕
The use of a mixture of sulfosuccinate collectors improved by fatty alcohol sulfates and the suppression of impurities with organic acids and sodium silicate directly flotates tin and removes zirconium, tantalum and niobite from the re-tin concentrate. With this method, 90% of the impurities can be removed from the tin concentrate. Tin concentrate grade can be increased from SnO 5 5% to 90%. The main influencing factor for the selective flotation of tin from tantalum, niobium and zirconium is capture
