摘要
pH值是影响矿物表面电性和药剂活性的重要因素。本文通过系统试验,详细研究了钛铁矿浮选过程中矿浆pH值对精矿品位和回收率的影响,发现4.5-5.5是钛铁矿浮选的最佳pH值区间。在此区间内,钛铁矿具有最佳的可浮性和选择性。根据浮选不同阶段对品位和回收率的不同要求,粗选和精选应分别选择5和4.5的pH值为宜。
It has been known that pH value is one of the important factors influencing mineral＇s surface charge and reagent activity in a flotation process.In this paper,the effect of pH value on the performance of ilmenite flotation is investigated.It is found that a pH value range of 4.5～5.5 is the best one for ilmenite flotation,within which ilmenite presents the most optimal floatability and selectivity.And pH values of 5 and 4.5 are considered to be the best pH values for roughing and cleaning respectively,according to the different demands for grade and recovery during different stages of the flotation process.
