    A study on selective flotation in low and high pyritic

    Despite numerous investigations on porphyry copper sulphides, there is still lack of knowledge on the selective flotation of chalcopyrite and pyrite in different ore types. Generally, grade and recovery are mainly used as metallurgical criteria to evaluate the performance of the flotation process.

    Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.
