stages and recycle lines. Column flotation devices were re-introduced for mineral processing in the late-1960's in Canada by Boutin and Wheeler (1967) at which time wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product. By the late-1980's column flotation had became a proven

Flotation columns and their variations are increasingly replacing conventional cells in mineral-processing circuits. While the operational characteristics of columns differ from those of conventional cells, the same scale-up methodologies are being employed. This practice may be attributed to a poor understanding of the factors that control throughput. The use of tall …

the introduction of column flotation. Flotation columns differ radically from conventional mechanical flotation units both in design and operating philosophy. This has been a cause of the reluctance to test these units industrially since their invention (in Canada) in the mid-60's by Boutin and Tremblay.


The heading of the floated column is hidden, so there is a risk where the column heading of the preceding column don't represent the content that was floated under. Please set column title wisely or if that column is a column header (link to technique about column header) then it can be deducted the content that is moved under is a middle ...

To prove commercial viability, Woodgrove installed and commissioned a Staged Flotation Reactor taking full throughput of a large copper concentrator. This study was completed on behalf of 10 of the largest global mining companies. An SFR solution was also installed and proven in 2010 at a gold operation in Canada.


Concentrate flow rates were measured for the flotation of −100-mesh Lower Kittaning coal in a computer-controlled 0.076 x 3.5-m pilot flotation column. The variables studied were recovery zone height, airflow and solid feed rates. The specific projected surface areas of the feed, concentrate and tailing streams were determined from the measured particle …
