  • Copper Flotation Mineral Processing Metallurgy

    Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and

  • Flotation of Pyrite Metallurgist Mineral Processing

    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.

    Copper must be assisting gold flotation as deciphered from the superior floatability of auricupride [Cu 3 Au] and tetra auricupride [AuCu] relative to native gold. At the Kemess flotation plant depending on the ore type (milled in separate campaigns), the role of some surface modifiers changes.

  • Pyrite Depressant Froth Flotation (Sulphide Oxide

    I experienced a copper gold massive ore type where thionocarbamate seemed to work better. Also, SMBS is a common pyrite depressant. Dithionocarbamates are very selective in copper flotation. It will not float pyrite. Can be used at a slightly elevated pH (9). It is a common approach in copper flotation.
