Dry mineral processing. In collaboration with Prof Jun Oshitani (Okayama Univ. of Science), we have developed a dry sand air fluidised bed dense medium float sink separation process for coal, iron ore and copper ores. The process has performance similar to conventional wet separation processes, but can save water and energy.

Froth Flotation is a mineral processing process achieving solid-solid separation by taking profit of the chemical attribute leading to the possibility of selectively controlling the relative surface hydrophobicities of the various components mixed in an aqueous medium. Froth flotation is the most common industrial process based on this approach.

Flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
