Column flotation deinking is a critical sub-system in paper recycling to produce the highest quality product at low cost. Among the benefits of column flotation are higher selectivity, smaller floor space requirement, lower capital cost and reduced operating and maintenance costs (Finch and Dobby, 1990).Vertical columns result in considerable floor space …
The mean froth residence time calculated using Eq. (3) takes into account only the vertical froth transportation and hence limits the model's application to small flotation cells and a narrow range of cell operating conditions. Realizing such limitations, several modified models were proposed within the P9 project: (4) R f = e −β·τ f /L where …

Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
Air is self-induced through a valve on the shaft. Alternately air can be supplied from a compressor and controlled by valve. What rotor speed is used on the D12 in a flotation test is a matter of personal choice or company standard. The speed affects the degree of agitation and the amount of air going into the cell and the number of air …
