Flotation in a novel oscillatory baffled column

Oct 01, 2009· Abstract. This paper presents an evaluation of an oscillatory baffled column (OBC) as a novel flotation device. The cell is based on a standard column design but employs a novel agitation mechanism where a series of baffle plates are oscillated sinusoidally through the fluid. This type of agitation has been shown to produce a more evenly

COLUMN FLOTATION MODELLING AND TECHNOLOGY

Industrial flotation columns are square or circular, typically 0.53m in diameter or side, and 1215m 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.

Chapter 9 Column Analysis and Design

Columns are used as major elements in trusses, building frames, and substructure supports for bridges (e.g. piers). Columns support compressive loads from roofs, floors, or bridge decks. Columns transmit the vertical forces to the foundations and into the subsoil. The work of a column is simpler than the work of a beam. The loads applied to a column
