the involvement of flotation size bubbles, typically in the range of 600 μm to 2 mm, is still required (Tao, 2005). Therefore it is suggested that the pico-bubbles be introduced into flotation cells to complement rather than replace flotation size bubbles (Nesset et al., 2006). Research has shown that

1. Introduction. Mining activities consume billions of m 3 of water annually. The water withdrawn by mining industries could achieve 17 m 3 per ton of processed ore while the water consumption required in processing varies between 0.34–6.27 m 3, according to data from 359 industries reports [1].Seeing that the world iron ore …

The test HF unit was installed in the flotation plant and was tested in a semi-continuous mode by using the +150-micron (100 mesh) size fraction of the plant flotation tailings as its feed. The initial study found that more than 50 % of gold from the tails resided in the above 150-micron size range which constitutes 40% tails mass.

The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. 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 constructed.

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.
