2.Copper-molybdenum mixed concentrate separation process . For the flotation separation of copper-molybdenum mixed concentrate, it can usually be divided into 3 steps. ① Pretreatment. The main purpose of pretreating the copper-molybdenum mixed concentrate is to remove the residual collectors in the slurry in the most reasonable and effective way.
Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and in the case of copper/ molybdenum ores separates molybdenite from copper sulphide.

When choosing ore which mainly contains molybdenum ore and a little copper, the technological process of part bulk preferential flotation is adopted. At present, molybdenum is recycled from copper molybdenum ore in China, the frequently used technological process is copper molybdenum bulk flotation, than to process separation between copper and
The usual grades for such polymetallic ore types are 0.3-0.6% copper, 0.1-0.2% zinc, and 0.1-0.01% molybdenum. The porphyritic ore features the tight intergrowth of sulfide minerals, and different sizes of sulfide minerals tend to show up. Based on this material composition, bulk sulfide flotation with further regrind and cleaning steps will be
The specification describes a method of recovering molybdenum from molybdenum containing ore wherein the ore is subjected to the conventional process steps of concentrating, roasting, and ammonia leaching followed by novel procedures to remove the copper from the leach solution without the necessity of adding an agent to precipitate the contaminant copper.
Mar 01, 2019· The copper-molybdenum ore concentration performance data, for the option of applying the developed flow sheet and procedure of recirculating water supply (presented in Table 4), is evidence that while maintaining the level of copper and molybdenum recovery, the grade of the copper and molybdenum concentrates is markedly increased (by 0.4% and 0
