Extracting from low grade ores FL

Extract copper and gold from lowgrade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 1520 per cent of the worlds current gold production involves refractory ores that must be pretreated prior to downstream recovery by cyanidation.

Effect of carbon on Cu/Pb/Zn flotation. Froth Flotation

This carbon adsorbs frother molecules like MIBC and very high additions of MIBC are required to get frothing (for preflotation). If one chooses to depress the carbon, rather than preflotation or reverse cleaning, for graphitic carbon the reagent naphthalene sulphonate is effective with dextrin but when the carbon is more like hydrocarbon, the
