颗粒在浮选泡沫中的行为。泡沫浮选被广泛用于矿物颗粒的分离。目前，对可处理的颗粒大小有一个上限。最近发现，通过处理泡沫中的颗粒，上限可以从几百微米扩展到毫米大小。我们将研究浮选泡沫中作用于颗粒的力，以及泡沫的排水和夹带，以找到限制大颗粒和物体浮选的因素。这项工作与水处理和塑料回收分离有关。

Behaviour of particles in flotation froths. Froth flotation is widely used for the separation of mineral particles. Currently, there is an upper limit on the size of particles that can be treated. It has recently been found that the upper limit can be extended from a few hundreds of microns, up to millimetre sizes, by processing the particles in the froth. We will study the forces acting on particles in flotation froths, as well as froth drainage and entrainment, to find the factors that limit the flotation of large particles and objects. The work is relevant to water treatment and the separation of plastics for recycling.
