The Molybdenum is a by-product of the copper production. The Molybdenum filter was installed to process the clarifier overflow to remove any remaining solids prior to sending the water for use in the Molybdenum floatation circuit. The water has to be free of solids larger than 5 micron to ensure proper floatation of the Molybdenum.
