Polymetallic Flotation Concentrator

This ore processing plant is for the flotation of 2 base metals (Cu/Pb/Zn/Co/Ni/etc.) which may or may not contain precious metals. These ore deposits are called polymetallic by geologists and metallurgists. This system allows you to recovery by way of differential or sequential flotatio, the sulphide metals in 2 separate concentrates. Examples include: Copper, Lead, Zinc, Cobalt, Nickel, Molybdenum, Pyrite, Pyrite-GoldSilver-Sulphides. This process will also recover silver and/or gold associated with sulphide minerals.

This simple metallurgical concentrator includes single stage crushing, conveying, primary grinding, hydrocyclone classification (optional spiral), slurry pumping, conditioning tanks, 2 rougher flotation circuits and 2 x 3 stages of concentrate dilution cleaning. For each or either metals, a regrind circuit can be added upon request.

If you know coarse gravity recoverable gold is present in your mineral deposit, an iCON gravity gold concentrator (and refinery) can easily by introduced in this process plant.

Our standard packages are for process plants of:

  • 25 Tonnes/Day = 1 Tonne/Hour
  • 50 Tonnes/Day = 2 Tonne/Hour
  • 100 Tonnes/Day = 4 Tonne/Hour
  • 250 Tonnes/Day = 10 Tonne/Hour

This is a standard process plant which includes only the major components of the complete metallurgical flowsheet. A detailed engineering study is required to identify unforeseen omissions that may be required to design the optimum plant.

Additionally, we offer two separate packages for plant tailings thickening/filtration and water treatment. Contact us for details.
