Cost-effective alternative for ultra-fine coal recovery

Conventional flotation circuits struggle to recover valuable ultra-fine coal particles (less than 45μm), leading to significant losses. Conventional technologies typically discard these ultra-fines, sacrificing valuable resources to tailings. Eriez's StackCell® and Flotation Column technologies have demonstrated superior efficiency in the area of ultra-fine coal recovery compared to conventional methods, thanks to their application of wash water over deep froths. When deployed as part of Somerset International's patented Sub325® Fine Coal Recovery System, which captures a very high proportion of ultra-fines to product, total recovery and yield is maximised, thereby also reducing tailings waste. The fine coal recovery system flowsheet offers significant advantages by creating revenue from a waste stream and reducing tailings volumes reporting to tailings storage facilities.
