In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse …

Flotation cell technology and circuit design—an Anglo Platinum perspective Pre 1980s—Mineral extraction circuits were charac-terized by multiple small flotation machines (typically 1m3) with short residence times, employing a single mill-float configuration. Typically a three-stage crushing, closed circuit ball mill comminution circuit
1949, Cominco used Maxwell cells to scalp rod mill discharge. The resulting concentrate was cleaned by a Denver cell. The Davcra cell, tested in the 1960s, was the first high-intensity flotation machine with a centrifugal feed stream and coarse tailings discharge, a precursor to today's flash flotation cell design.

The Air Flow Number should lie within a narrow range for optimum flotation results for any one cell. Harris gives values for most commercial cells while Table 4 has more detailed data for Denver and Wemco cells based on more recent measurements for sizes up to over 30m (1,000 cu. ft.).
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
As shown in the water system flow diagram (Fig. 12.12), the total mill effluent is collected in tank [2] and pumped to the first flotation cell [4]. Part of the clarified water from flotation cell [4] is pumped from tank [5] to the second flotation cell [6].
