What is forth flotation |
| Answer» Definition of froth flotation: flotation in which air bubbles are introduced into a mixture of finely divided ore or other material with water and a chemical that aids attachment of the bubbles to the particles of the desired material and its recovery as a frothFroth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores".[1] The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously.https://upload.wikimedia.org/wikipedia/commons/d/d0/Flotation_cell.jpghttps://upload.wikimedia.org/wikipedia/commons/thumb/0/04/Froth_Flotation_Plant_at_Argonne.jpg/800px-Froth_Flotation_Plant_at_Argonne.jpghttps://upload.wikimedia.org/wikipedia/commons/f/fd/FlotationFalconbridgeOnt.jpghttps://upload.wikimedia.org/wikipedia/commons/1/19/FlCell.PNGhttps://upload.wikimedia.org/wikipedia/commons/thumb/e/e7/Prominenthill-flotation.jpg/800px-Prominenthill-flotation.jpg | |
