Chalcopyrite and molybdenite had a good recovery (over 90%) at pH 6–12. However, when using DTT as a depressant, the floatability of chalcopyrite decreased drastically, obtaining a recovery of 8% (pH 9–12). In the case of molybdenite, it was not influenced by DTT, confirming that this depressant is an excellent alternative for Cu–Mo ...

4. Beneficiation Reagents for Molybdenum Ores 4.1.Collectors Hydrocarbon oil is the most commonly used collector for molybdenite flotation separation. Among hydrocarbon oils, kerosene, diesel and aromatic hydrocarbons are the most commonly used. Most domestic molybdenum and copper-molybdenum beneficiation plants in China use kerosene, and …

K = F /C = (c — t)/ (f-t) = the concentration ratio. At operating plants, it is usually simpler to report the K based on assays. If more than one mineral or metal is recovered in a bulk concentrate, each will have its own K with the one regarded as most important being reported as the plant criteria.

Tungsten beneficiation plants normally operate with a recovery of 60–85%. The beneficiation recovery rate for the Mittersill tungsten mine in Austria has been …

Sodium hydrogen sulfide (NaHS) is commonly used as a copper depressant in the selective flotation of copper and molybdenum ores. However, the process is facing health and safety issues because NaHS readily yields toxic hydrogen sulfide gas (H2S) under acidic conditions. In this study, Na2SO3 was proposed as an alternative copper …
