Abstract

The device comprises an array of flotation cells which are in serial fluid flow communication from a first inflow cell to a final outflow cell, the first cell having fluid inlet device for introducing fluid into the device and the final cell having fluid outlet device for removing fluid from the device. There is an overflow receiving device being in overflow fluid flow communication with each cell. There is an air inlet device positioned in a lower region of each cell for introducing compressed air into each cell, and mechanical agitation device for each cell, and internal surfaces for each cell which are shaped and oriented to provide in conjunction with inflowing compressed air and mechanical agitation an upright circular fluid flow in each cell toward the overflow receiving device.
