Flash flotation – an introduction AusIMM Bulletin

Flash flotation is the instantaneous flotation of fast floating valuable mineral particles from the grinding circuit to produce a suitable grade concentrate. A flash flotation cell recovers liberated valuable minerals in the cyclone underflow (recirculating load) before they return to the mill for further grinding.
