2016-6-8  In mid-2011, six 300 m3 float cells were commissioned, four cells dedicated to the sulphide flotation circuit and the other two being flexible between mixed and sulphide ore flotation, depending on milling circuit configuration. The volume capacity of the mixed ore flotation plant increased from 900 m3 to 1500 m3 or 2100 m3, depending on whether the 300 m3 cells are used for mixed ore flotation or not.

1 Froth Flotation – Fundamental Principles

2009-8-27  The collectors available for flotation of oxide minerals are not as selective as the collectors used for sulfide mineral flotation, as they attach to the surface by electrostatic attraction rather than by chemically bonding to the surface. As a result, there is some collector adsorption onto the minerals that are not intended to float.
