WebNov 1, 2011 · Jameson Cells acting as a prefloat cell at the head of a rougher circuit, or treating the hydrophobic gangue as a prefloat rougher cleaner, is an ideal way to produce a ‘throw away’ product before flotation of the valuable minerals, minimising reagent use and circulating loads. WebFlotation oils act as co-collectors, extending the collector’s ability to float the desired mineral. They provide strength to the hydrophobic layer. The amount and type of flotation oil used can directly impact the nature of the froth, and thus can control the strength and selectivity of the froth zone. Oil imparts hydrophobicity to mineral ...

Froth Flotation Process - Mineral Processing
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 … See more Froth flotation is applied to a wide range of separations. An estimated 1B tons of materials are processed in this manner annually. Mineral processing Froth flotation is a … See more Flotation can be performed in rectangular or cylindrical mechanically agitated cells or tanks, flotation columns, Jameson Cells or deinking flotation … See more Sulfide ores Copper (see copper extraction) and copper-molybdenum Lead-Zinc Prior to 1907, nearly all the copper mined in the US came from … See more The ore to be treated is ground into particles (comminution).
