The goal of the work was verification of floatabilty of bituminous coal from mine Staszicz with different collectors (Flotalex and Montanol), which are generally used in coal cleaning plants in Czech Republic and Poland. From the flotation and petrological results follows that floatability of given coal is approximately equal at Flotalex and Montanol application.
