如果保证浮选过程的选择性不是首要任务 ,那么可以在浮选中应用选择性较差的起泡剂 ,以提高矿物的回收率。通过改变烃链长度和引入电子供体原子来增大起泡剂疏水 -亲脂平衡值 ,可以降低其表面活性 ,增强其捕收力。在铜钼矿石浮选中应用ΦPИM型亲脂性高的起泡剂既可代替选择性高的MIBC起泡剂 ,也可与主捕收剂和主起泡剂混合应用 ,提高精矿回收率和品位 ,减少捕收剂和起泡剂的用量。
If it is not the primary task to ensure the selectivity of the flotation process, less selective foaming agents can be used in the flotation to increase mineral recovery. By changing the length of the hydrocarbon chain and introducing electron donor atoms to increase the hydrophobic-lipophilic balance of the foaming agent, the surface activity can be decreased and the catching power can be enhanced. In the flotation of copper and molybdenum ФPИM-type lipophilic high foaming agent can replace the high selectivity of MIBC foaming agent can also be combined with the main collector and the main blowing agent to improve the recovery rate and Grade, reducing the amount of collectors and foaming agent.
