Flash flotation – an introduction AusIMM Bulletin

Typical applications of flash flotation can be found in gold, silver, platinum and other PGMs, lead, copper, nickel, and combinations thereof. It is worth noting that typically flash flotation is not extensively evaluated during a feasibility study and hence it is unknown if it would be

Flash Flotation with Closed Circuit Grinding

The reason why you need Flash Flotation in a Closed Grinding Circuit relates to “Recovering your mineral as soon as free” which has long been recognized in ore dressing practice. This not only applies to gravity treatment but also to flotation. For this application the Flash Flotation Cell was developed for use in the grinding circuit and has done a remarkable job in many plants. Flotation
