Coal beneficiation using a CoalPro flotation column were evaluated. A microbubble flotation column, commercially known as the Microcel, was developed by Yoon et al. [140,141] to treat very fine particles. As a result, large quantities of small bubbles were generated and shown to be very effective in ultrafine coal processing.
