In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be ...

The sulphide ores are universally treated by flotation, and the major gangue components include a host of MgO minerals, such as serpentine. MgO minerals (e.g. serpentines) break readily. Thus grinding produces fines or slimes, particles less than approximately ...

The lack of very fine sulphide development and sulphide veining suggests that sulphides within the NP2 reef will be the easiest to liberate as is the case for chalcopyrite, pyrrhotite and the composite BMS (Brough et al., 2010).

It looks like flotation is not the way to go with this sample we've had success doing the separation using gravity and its hardness, the fines being the serpentine gangue. The bag given to me was a pulverized sample from our chemist so I had a new batch made up which I later grounded to P80=200 um.
