AI Technical Summary
Technical Problem
Existing technologies are insufficient for efficiently desorbing fatty acid collectors from flotation concentrates, leading to reagent loss, difficulties in the smelting process, and increased wastewater treatment costs.
Method used
The desorption process is carried out in an acidic solution with stirring, the pH is controlled to be less than or equal to 4.0, the temperature is 0 to 10℃, and the stirring speed is above 1000 r/min. Combined with solid-liquid separation, the desorption process is optimized to achieve selective desorption and reuse of the collector.
Benefits of technology
This technology enables efficient desorption and reuse of fatty acid collectors, reduces reagent loss and wastewater treatment costs, and improves concentrate quality and smelting efficiency.

Abstract
本发明属于矿物浮选以及药剂回用技术领域，具体公开了一种浮选精矿中捕收剂的解吸方法，将浮选精矿在酸液中进行搅拌解吸处理，随后固液分离，得到解吸后的精矿；其中，解吸阶段中，体系的pH小于或等于4.0，温度为0～10℃；解吸处理阶段的搅拌转速在1000r / min以上；所述的浮选精矿包括矿物以及键合在其表面的捕收剂；其中，所述的捕收剂包含有机酸捕收剂。本发明创新地发现，创新地将有机酸浮选的精矿在酸液中解吸，配合处理阶段的pH、搅拌以及温度的联合控制，可以实现协同，可以改善精矿中的有机酸捕收剂和矿物的解吸效果，不仅如此，还利于避免脱附所致的捕收剂失效劣化，还可降低处理后的溶液的COD含量。
