ABSTRACT

Coal is one of the main energy sources in Turkey; it is used for both domestic heating
and energy generation in power plants. However, most of these coals have low calorific
value, high ash and sulfur content and high slagging potential. Therefore, they usually
need to be cleaned before using in heating or power generation. Coal preparation
operations consider the removal of ash forming material from the Run-of-Mine (ROM)
coal. Dense-medium separators are employed in the majority of coal preparation plants
for this purpose in Turkey. In this study, the effect of coal cleaning process on the
quality and slagging potential of Bagyaka coal were investigated by the application of
float-sink tests.

Keywords: coal cleaning, slagging potential, float-sink tests
