Floatation Behavior and Mechanism of Quartz Using Amphoteric Collector LDS
-
Abstract
The flotation performance of quartz using LDS as collector was investigated.The interaction mechanism of LDS and quartz was discussed via contact angle measurement,zeta potential test,infrared spectrum analysis and pyrene fluorescence spectrum analysis.The results showed that under the condition of pH 4.0~4.5 and the dosage of LDS 90 mg/L,the recovery of quartz could reach 97.5%.Based on the results of angle measurement,zeta potential test,infrared spectrum analysis and pyrene fluorescence spectrum analysis,it was found that under the acidic condition,LDS adsorbed on the surface of quartz mainly by Van der Waals forces.When the concentration of LDS was more than 60 mg/L,the double layer adsorption film might be formed on the surface of quartz. -
