  Minerals | Free Full-Text | Utilization of Flotation Wastewater …

  202448 · In the flotation separation process of a Cu-Mo-W polymetallic ore, the wastewater from the scheelite cleaning flowsheet contains large numbers of residual flocculants and metal ions, and the separation of chalcopyrite and molybdenite requires a large number of environmentally harmful depressants. Therefore, it is necessary to find …

  Recent progress on research of molybdenite flotation: A review

  202191 · Abstract. Molybdenum is an important alloy element for metallurgical industry because of its high temperature stability. As the major mineral reserve for molybdenum, molybdenite (MoS 2) is commonly found in porphyry copper deposits. Molybdenite is naturally floatable and can be separated from copper sulfide mineral using …

  Sulfide Flotation - an overview | ScienceDirect Topics

  The Batu Hijau Concentrator uses sea water for processing a gold-rich phorphyry copper ore (chalcopyrite-bornite) (Castro, 2012), while CBI processes a complex Cu–Zn sulphide ore using dissolved metal ions and sulphide ions, mainly in the form of SO 4 2 − and S 2 O 3 2 − (Bıçak et al., 2012).
