Column and Contact Cell Flotation | SGS

Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation reagents. However, in column flotation, there is no ...

ABSTRACT. The application of cyclonic microbubble flotation column (FCMC) from laboratory to industrial scale was investigated in this study. The FCMC was found to be superior to the standard self-aeration flotation cell for separating the fine coal (below 0.5 mm in size) as sampled from the Xiezhuang coal preparation plant (CPP), and tested under laboratory conditions.

COLUMN FLOTATION MODELLING AND TECHNOLOGY

Industrial flotation columns are square or circular, typically 0.5-3m in diameter or side, and 12-15m height. Since their invention, square columns have been marketed commercially by the Column Flotation Company of Canada Ltd. The apparent simplicity of the column has led others to copy the original idea and make their own "homemade" columns.
