Ion Flotation a metal recovery technique European
So far, ion flotation hasn’t been used successfully for the recovery of metals from leachates in the tailings reprocessing On the other hand, a similar flotation technique – froth flotation is readily used in the recovery of sulfide ores, but its application in flotation of tailings is impeded because of the size of the tailing particlesFroth 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 centuryFroth flotation Wikipedia
