Iron ore slimes flotation - ScienceDirect

2010-10-1  Vieira (2009) developed a process for the concentration of tailings from the mechanical machines flotation circuit of a large iron ore concentrator in Brazil, consisting of a mixed circuit, wet high intensity magnetic separation (WHIMS) followed by cationic reverse flotation. The rougher WHIMS stage yielded an iron pre-concentrate (34% Fe) at recovery level of 80%.

Flotation Process - an overview ScienceDirect Topics

The linear structure of the flotation cells has a large surface area, which has reject separation and fiber loss. This flotation cell design also contributes to high sludge consistency (less water in the sludge) by ensuring smooth drainage of froth (Aksela, 2008). The elliptical shape of the flotation cells in this technology is optimal for internal pulp circulation for improved ink removal.
