In a copper‑molybdenum processing plant, copper sulfide concentrate (such as chalcopyrite) is floated together with molybdenite in the first stage. [7] The separation of molybdenite and copper sulfide is achieved in the second stage through flotation. [8] In most scenarios, copper sulfides, such as chalcopyrite, are depressed using a depressant (e.g. …
The coarse molybdenum concentrate is reground in two or three stages, and the final molybdenum concentrate is obtained by four or five times of selection. The flotation reagent of molybdenum ore uses non-polar oils as collectors, while adding ing agents. The United States and Canada use the surfactant Syntex as an oil emulsifier.
