The G-Cells are operated in closed circuit, with the tails from the second G-Cell reporting to the first G-Cell and the tails from the first cell reporting back to the flotation feed. Each G-Cell gives a two times upgrade; rougher concentrate at 10g/t Au is upgraded to 20g/t Au in the first G-Cell and then further to 40g/t Au in the second G-Cell.

CFD model of a self-aerating flotation cell - ScienceDirect

Dec 05, 2007  1. Introduction. Flotation is an important process in the minerals industry and most flotation is carried out using mechanically agitated cells ranging in volume up to 300 m 3.Separation of the particles of valuable minerals from the ore is achieved when particles of the valuable minerals preferentially attach to air bubbles and are floated to the surface of the slurry via a froth layer.

Jameson cell - Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for ...
