Beneficiation strategy for a medium coking coal fines from India has been studied. These coal fines have good washability characteristics indicating about 60% yield at 14% ash in clean coal. But the release analysis results indicate poor flotability of these fines. Only about 30% yield was achievable at 14% ash in the clean coal. Various schemes for flotation including two-stage flotation, split flotation, spiral, and a combination of spiral and flotation were studied using a 15-cm diameter Jameson Cell. Combination of spiral and Jameson Cell flotation achieved approximately 69% yield at 17.5% ash.
