A Molybdenum Flotation case study with about 6% of the molybdenum contained in the feed is present as an oxide form and about 90% of this is not recovered to the flotation concentrate. Recovery of molybdenum into the rougher concentrate varied between 90 to 95% at a concentrate grade of 2.5 to 3.7% molybdenum. The rougher concentrate can be ...
The molybdenum leach plant at Teck Highland Valley Copper Partnership leaches copper minerals out of the molybdenum concentrate in order to produce a saleable product. The plant is in need of capital investment to continue operating safely for the remainder of mine life. Management has initiated a technical investigation into the
The demand for molybdenum in the Chinese market can provide a base for growth in prices in the future. The global production of molybdenum is about 220 thous tons of metal per annum. Armenian mining companies produced 8.5 thous tons of molybdenum concentrate in 2010.
