high intensity flotation

The Concorde Cell™ sets a new benchmark in high intensity pneumatic flotation by recovering unachievable fine and ultra-fine particles. This results in significant revenue gains for your operation as well as minimizes plant operating costs, energy and water consumption per metal production targets.

In this technique, a jet is used to induce air to generate the bubble to make froth. Microcell, Davcra cell, and Bahr cell are examples of this type of flotation. These flotation machines are high-intensity flotation machines. The schematic of Jameson flotation cell is shown in Fig. 2. Download : Download high-res image (208KB)

Conventional flotation technology has historically failed to achieve high recoveries when treating <15 m particles (Lynch et al, 1981).

The high intensity conditioning process, HIC, as it has been named, enhanced the flotation recovery of the very fine particles of copper sulfides (Bulatovic and Salter, 1989), gold, uranium oxide and pyrite fines (Stassen, 1990, 1991) and oxidized copper ores and copper and molybdenum sulfides (Rubio, 1978; Rubio and de Brum, 1994).

It has been found that High Intensity Conditioning (HIC) significantly increases the flotation rate of pentlandite from a nickel ore.

High Intensity Conditioning improved pentlandite flotation from a nickel ore. Specifically, High Intensity Conditioning increased the flotation rate of pentlandite contained in the 8 to 75 μm particle size range. There was also a significant increase in the maximum recovery of pentlandite over the same particle size range.
