COLUMN FLOTATION MODELLING AND TECHNOLOGY

Industrial flotation columns are square or circular typically 05-3m 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...

Unconventional column flotation of low

28-03-2008 0183 32 A flotation column is a reactor composed mainly of a collection zone and a froth zone The collection zone has the objective of attaching hydrophobic particles to bubbles and the froth zone is responsible for the carrying capacity and froth enrichment Finch and Dobby 1990 Dobby and Finch 1991 The drop-back material from the froth returns to the collection zone goes back to froth in...
