Study on Electrochemical Flotation of Low Rank Coal Macerals

Coal component is the basic unit of coal, each component of coal has its special processing properties, Now under the demand of energy conservation and environmental protection , how to sort coal components reasonably and effectively has become a problem needed to resolve immediately. Picking vitrain and fusain by hand, analyzing the pH and add in different solution under the condition of different drugs both surface potential difference, and through the flotation tests determine the appropriate separation conditions. The results show that the enrichment rate of the maceral have improved by electrochemical flotation method .
