Here Peter Bourke, Outotec's global technology manager–flotation process and Alan Berzins, project manager–minerals processing, discuss the installation. Macraes gold was a two train plant. Each train consisted of an Outotec Flash flotation cell on the cyclone underflow which recovered 50%65% of the sulphide price
· "The first SkimAir flash flotation cell was installed in Outokumpu's Hammaslahti Copper Concentrator in 1982 to prevent overgrinding of soft sulphides in the milling circuit. Since this first installation the popularity of the flash flotation has fluctuated depending on metal market conditions and regional preferences. Units have been installed in many commodities including copper, lead ...
