mechanical flotation cell. [ mikankl fltshn sel] (mining engineering) A device that separates minerals from ore water pulp; it consists of a cell in which the pulp is kept mixed and moving by an impeller at the bottom of the cell; the impeller pulls air down the standpipe and disperses it as bubbles through the pulp

The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs. Also, it has been reported that the cost of installing a column flotation circuit is approximately 2540% less than an equivalent mechanical flotation circuit (Murdock et al., 1991)

In treating oily water from oil refineries, the separation of oil by mechanical flotation is called froth flotation. It is achieved by adding an organic coagulant or demulsifying agent. Flotation units are constructed with three or four cells in series. Froth flotation by injection of air may also be used for the separation of surfactants

In column flotation air bubble agitation is not sufficient to keep large particles in suspension so that residence times are short in comparison to a bank of mechanical flotation cells. Originally developed in Canada in the 1960s as cleaning cells, this type of cell has become common in the flotation circuit of new plants, as both roughing and
