The relationship between anion distribution in process

Author: Min Tang, Xiong Tong

Sulphate Removal from Flotation Process Water Using

A strong base anion ion exchange resin (Selion SBA2000) was used in the experiments. The findings from the laboratory scale studies were validated in a Cu-Pb-Zn Flotation Plant in an Iberian mine using a larger scale of column set-up. The results showed that 60–70% of sulphates could be successfully removed from process water.

The relationship between anion distribution in process

They could alter the chemistry of a flotation system and interfere with the interaction between minerals and reagents. The purpose of this study was to identify the relationship between anion distribution in the process water and the flotation performance of a typical industrial iron ore concentrator when the process conditions were stable.

Reaction of sulfur anions with quaternary ammonium

2020-7-8  The interaction of the SO/sub 4//sup 2 -/ anion with quaternary ammonium salts in the process of foam flotation takes place mainly by an ion-exchange mechanism. The presence of electrolytes (acid, alkali, salt) in solution leads to the suppression of the interaction because of the competing influence of the anions present.
