Abstract

In this study we have used wet separation techniques for selective flotation of the low rank Sulcis coal. The investigation has been carried out for cleaning waste coal fines from the Nuraxi Figus treatment plant with a view to using the concentrate in the power industry. The results of this investigation have shown that the proportion of coal fines recovered ranged between 50 and 60%, depending on desired concentrate quality. Moreover, a market has been identified on the basis of concentrate characteristics.
