Surface characteristics and hydrodynamics in detachment of coarse particles (2015–2018)
Froth flotation is widely used for separating coal and minerals from the gangue. The largest particles that can
be floated in the industry are 10 times smaller than the particles that can be floated under quiescent
conditions. This project aims to better understand and quantify the detachment of large particles from the
bubble surface. It will develop innovative modeling and experimental approaches to examine the effect of
particle surface characteristics and hydrodynamic conditions on coarse particle detachment and flotation.
New ways to save energy by floating coarse composite particles will be developed. This research is at the
forefront of flotation science and technology, and will deliver significant outcomes to the mining industry.
