Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence, Increase its …
The crushed ore is sent by the 4.4km conveyer to the grinding plant, which houses one 40ft SAG mill and two 26ft ball mills. The ore slurry prepared from the milled ore is sent to the Las Tórtolas flotation plant through a 52km pipeline. The slurry undergoes froth flotation for separating the copper and molybdenum concentrates.
1 The crushed molybdenum ore is sent to a ball mill for grinding. The molybdenum disulfide powder has a diameter of only a few microns. 2 Then it is screened by a spiral classifier. The qualified molybdenum powders are sent to the floatation machine, while the rest continues to be ground. Stage III Molybdenum flotation
1. Grinding. A grinding machine crushes rocks the size of footballs to the size of gravel, then uses a ball mill to further reduce the material to the size of cosmetic powder. Thompson Creek molybdenum ore. 2. Flotation. In the flotation process, the ground ore/gangue powder is mixed with a liquid reagent and inflated.
The invention discloses a flotation separation method for molybdenite and galena, which comprises the following steps of: 1, rough grinding; 2, rough selection and scavenging for obtaining lead-containing molybdenum rough concentrate; 3, regrinding after a certain amount of active carbon is added into the lead-containing molybdenum rough concentrate; and 4, …

Flotation 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.

Flotation studies were performed on laboratory flo-tation machines with chamber volumes of 3; 1,0; 0,5 liters. The mass of the ore charge was 1 kg. Experiments were performed in open and closed cycles. The flotation scheme included grinding, main flotation, control, and three cleaning operations of the collective copper-mo-lybdenum concentration.
Introduction. Flotation is the common copper processing technology, which can be used for sulfide ore and oxide ore. The copper flotation plant usually includes following steps: crushing and screening, stage grinding and flotation, thickening and dewatering, and copper concentrates recovery.
