面向氯化钾浮选分离过程的超声强化
Strengthening flotation of potassium chloride using the ultrasonic pretreatment
摘要
Abstract
The objective of this paper is to improve the recovery of soluble potassium chloride flotation by ultrasonic pretreatment. Particles treated by ultrasonic wave had rough surfaces and were ellipsoid shaped,verified by the scanning electron microscope. The flotation results of ultrasonic wave treated potassium chloride particles revealed that the potassium chloride particles recovery increased from 14.32% to 46.66% after treated for 40min. Besides,the ultrasonic wave treated collector,i.e., octadecylamine hydrochloride,had better dispersity in the saturated potassium chloride solutions than the untreated one,resulting in a higher flotation recovery. The potassium chloride particles recovery increased from 20.84% to 94.24% when the octadecylamine hydrochloride was treated for 20min using ultrasonic wave. Therefore,the ultrasonic pretreatment was proven to be one of the effective methods to strengthen the flotation of potassium chloride.关键词
