 · Triboelectrostatic separation efficiency can be improved by screening fly ash in the narrow particle size under 74 μm, and the separation effect of narrow size grain samples obtained after screening is better than the fullsize grain ones. Therefore, the fly ash should be screened properly before separation.

experimental study on fly ash with different moisture contents. It can be concluded that the microwave heating process was efficiently applied for the wet fly ash triboelectrostatic beneficiation. Keywords: wet fly ash, triboelectrostatic beneficiation, microwave heating, efficiency Introduction

This bottom ash from waste incinerators contains up to 90% mineral traces, 48% ferrous metals and roughly 2% nonferrous metals. To make the exploitation of bottom ash possible, the most complete possible separation of the metal components is essential.

triboelectrostatic or a wet agglomeration column technique. Dry Separation of Fly Ash Triboelectrostatic beneficiation of fly ash to remove unburned carbon has been investigated recently [12] . During triboelectrifiion, organic and mineral particles are charged with opposite polarity and separate d by using an electrostatic separator.
