Introduction

Sorting flotation is widely used in pulverized coal (mud), and pulverized coal (mud) floatability is determined by laboratory tests.

This section provides the main laboratory parameters, test conditions and test procedure and other flotation machine. Its purpose is to guide the pulverized coal (mud) can

Experimental study on floating and assessment.
