This article presents the results of pilot-scale studies of ash and sulfur removal from a Turkish coal
by using the cyclojet flotation cell. The cyclojet cell, which was developed by H. Hacifazlioglu and I.
Toroglu in 2006, utilizes an alternative jet flotation technique. Apart from being based on the working
principle of jet flotation, the cyclojet cell incorporates centrifugal forces into the flotation process, thus
providing an excellent separation for ash and pyritic sulfur removal. The most important parameters
for the removal of ash and pyritic sulfur in the cycojet cell are the length of the conical jet, frother
type, wash water rate, and froth thickness. With decreasing the conical jet length and increasing the
wash water rate and froth thickness, there is an increase in the removal of pyritic sulfur. On the
other hand, the frothing agents MIBC produced better results in terms of pyritic sulfur removal in the
cyclojet cell. Under optimal conditions, the cyclojet cell removed 61.25% of the pyritic sulfur and
73.98% of the ash with a combustible recovery value of 71.10% without any need for a depressant.
