Details1949, 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.
DetailsIn simulation III, it is possible to identify a higher volumetric flow of pulp fed to the flash cell (28.7 m 3 /h to 58.6 m 3 /h; decreasing the P 80 in flash flotation feed), which is directly related to the recovery of fine particles with gold and silver (see Fig. 6 (a-d)).

DetailsFlotation equipment such as mechanical flotation cells and flotation columns are commonly designed to provide even dispersal of bubbles within the pulp zone of the tank. The mapping of void fraction in the volume surrounding the downcomer for air to pulp ratios of 0.3, 0.54, and 0.94 shows that this is not the case for the Jameson Cell, …

It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was …
DetailsIn the Jameson cell slurry and air are introduced at the top which proceeds downward in the downcomer and forms a liquid jet. Consequently, air is entrained into the plunging jet because of the vacuum effect and generates a large number of tiny bubbles as a result of high shear rate [55].In the downcomer region, the collection of particles on …
