Froth 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. The development of frothflotation has improved the recovery of v
This book presents the analysis of a wide range of problems in the process theory of flotation columns, including the first published analysis of models of flotation froths. The experience of pilot testsmercial applications of column flotation for mineral processing and in waste water treatment circuits are also considered. This is the first book to consider column flotation
Dissolved air flotation DAF is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter
