Rougher Flotation Cells - Mining and Mineral Processing ...

Rougher Cells will receive the feeding material flow from the ball mill. So flotation cells in this stage have bigger working volume than the cleaner flotation cells and scavenger cells. Rougher cells also have 2 types, mechnical agitation with self- absorbtion air cells and Pneumatic flotation cells. Choosing the different type according to ...

The Advantages of the Imhoflot G-Cell Pneumatic

2021-12-16  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.
