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. …

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or …
