Dissecting the Flotation Process. Conventional flotation cells are known to be relatively inefficient in terms of promoting particlebubble contacting. However, the historical approach is to compensate by adding a scaleup factor to the residence time obtained through benchscale tests. This approach is increasingly limited in circuits, which ...

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

Flotation is a physiochemical process that utilises particles' physical attachment to bubbles to separate minerals by floating them to the surface of flotation cells. Hydrophobic (or water repelling) surfaces can attach to bubbles and be floated, whereas hydrophilic (or water attracting) surfaces cannot.
