Abstract

Abstract:

The coal slime is difficult sedimentation because of montmorillonite easily expansion and hydration to form colloidal suspensions. In order to suppress montmorillonite expansion and hydration, using its sedimentation experimental results, to analyze the effects of different electrolytes. The results indicate that K+ solution can inhibit expansion and hydration of montmorillonite and improve its sedimentation characteristics significantly. Moreover the amount of flocculant was reduced greatly. The effects of this method for flotation was studied, and the results showed that this effects was little. Therefore this coal slurry treatment may be used as the coal preparation plant with more montmorillonite.

Key words: coal slime, montmorillonite, expansion and hydration, sedimentation
