Froth flotation Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing, paper recycling and wastewater treatment industries Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th centuryThe flotation rate of the chalcopyrite ore is 08 min a If choose the Wemco 85 m² cells, determine the number of cells needed to achieve >90% recovery of chalcopyrite Question: A process engineer is designing a cleaner flotation bank that will be treating 2500 m3/h of chalcopyrite concentrate from a rougher flotation cell The flotation A process engineer is designing a cleaner flotation Nov 01, 2011 The mine, which has produced more than 2 Moz in its 26year history, previously employed a flotation circuit consisting of a bank of eight mechanical trough cells in the rougher circuit, followed by two banks of 2 x OK3 Outotec cells as cleaners The feed rate to the cells was between 90105 t/h, at 5055% solidsMineral Flotation International Mining
