Comparison of Froth Flotation and Reflux Classification

In South Africa, over 10 million tons of ultrafine coal wastes are discarded every year, typically in the form of ultrafine slurries. These fines have high sulfur content which contributes to adverse environmental effects such as acid rock drainage (ARD). This book investigates the effectiveness of combining flotation and reflux classification for removing sulfide minerals from two South African coal ultrafines, whilst recovering valuable coal. The results will help shed some light in the capability of using both methods together in mitigating ARD.
