Molybdenum Ore Processing by Flotation. This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue. It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores.
Copper-Molybdenum ores Molybdenite (MoS2) is the predominant economic molybdenum mineral. While naturally very hydrophobic and can effectively be floated with just frother, addition of a hydrocarbon oil extender enhances its recovery.
The development drilling program of the Copper Cities mine indicated that the molybdenum content of the ore would be about % MoS2. The molybdenum content of the Miami mine at the same time was about % M0S2.
Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it’s rarely adopted in industrial production. In part combined flotation process, molybdenum with high floatability will be concentrated first, and then copper and molybdenum combined concentrate are concentrated together.
In the case of copper–molybdenum separation, chalcopyrite (CuFeS 2) and molybdenite (MoS 2) are the main copper and molybdenum minerals found in complex sul?de ores.
The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
In this work rougher flotation tests were conducted with two copper ores at laboratory flotation scale under standard industrial conditions, and Cu and Mo recoveries were calculated as a function of pH with sea water and tap water. Subsequently, frothing experiments were conducted with the same copper ores and flotation conditions,
Under the flotation condition of MC-103 64 g, and rougher pH for high-oxided ore and pH for normal ore, the effects of the particle size distributions of rougher pulp slurry on the recoveries and grades of copper and molybdenum in the Cu–Mo rougher concentrates were shown in Fig. 5. It indicated that with the increase of the ratio of slurry particles passed 76 μm, the recoveries of Mo and Cu increased and the grades of Mo and Cu slightly decreased.
molybdenum industry in the world. In this context, the aim of this study was to evaluate the flotation behavior of low-grade porphyry copper-molybdenum ore obtained from the Kirklareli region of Turkey. The ore sample used in this study contained % Mo and % Cu.
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. The resulting MoS2 concentrate contains between 85% and 92% MoS2.
Molybdenite (MoS2) is the predominant economic molybdenum mineral. Further, because optimum moly flotation pH is at 7-8 while optimum copper selectivity
