For various sorts of hard coal, enrichment by flotation is used for feed consisting grains smaller than 0.5 mm. Regarding process automation, coal a multidimensional, dynamic nonlinear object control, which the main control signal flow rate agent. Typically, in Polish coal-processing facilities monitoring and systems can only measure parameter waste quality (content ash tailings). This naturall...

The aim of this study is to compare the effect of the ultrasonic pre treatment on the removal of heavy metals (Iron, Zinc and Copper) from Acid Mine Drainage (AMD) by Denver Cell flotation. Synthetic AMD and individual metal solutions are used in the initial experiments to optimise the process conditions for real AMD. Three different process methods, ultrasound treatment followed by Denver flot...
