A comparison of anionic and cationic flotation of a siliceous phosphate rock in a column flotation cell

筹款性能一软泥 de (? 150 + 53 渭 m ) 约旦的硅质的磷酸盐在 100 厘米高的批实验室筹款列和 5 厘米里面被评估直径。当胺醋酸盐(AEROMINE 3100C ) 被用于 cationic 筹款时，在 anionic 筹款期间使用的收集者是钠油酸盐。在不同收集者剂量，表面的煤气的速度，和 frother 集中的筹款比较证明在在 cationic 和 anionic 筹款之间的性能的最大的差别与这些筹款参数被获得：30 脳 10 ? 6 (mg/L ) frother 集中， 250 g/t 收集者集中，和 3.4 cm/s 表面的煤气的速度。在这些操作条件胺(cationic ) ，筹款给了 7% 更高的筹款恢复， 6% 清洁工集中等级，并且是在搬迁有效的 6% 更多硅石。

Flotation performance of a de-slimed（-150＋53μm）Jordanian siliceous phosphate was evaluated in a batch laboratory flotation column 100 cm high and 5 cm inside diameter.The collector used during anionic flotation was sodium oleate while an amine acetate（AEROMINE 3100C）was used for cationic flotation.Flotation comparison at different collector dosage,superficial gas velocity,and frother concentration showed that the maximum difference in performance between cationic and anionic flotation was obtained with these flotation parameters：30×10^（-6）（mg/L）frother concentration,250 g/t collector concentration,and 3.4 cm/s superficial gas velocity.At these operating conditions amine （cationic）flotation gave 7%higher flotation recovery,a 6%cleaner concentrate grade,and was 6%more efficient at removing silica.
