    Investigation of Flotation Parameters for Copper Recovery

    At pH 11 enargite recovery increased to 73% giving an increased copper grade of 37.01mass%, and this was attributed to by decreased pyrite recovery of up to 20%. However, As content in the nal tailings was higher at 2.40mass% due to reduced recovery of enargite.

    The Importance of pH in Flotation

    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

    Nitogen and carbon dioxide gases are also used for galena depression. Galena flotation is preferred at lower pH than sphalerite. Lime is used to control pH and to depress pyrite but it can depress galena to some extent. For activation of sphalerite, use of copper sulphate is universally practised.
