oxidized ore in mineral processing

Oxidized Mineral - an overview | ScienceDirect Topics

Oxidized Mineral. Oxidized minerals of lead, zinc, and copper, such as cerussite, smithsonite, azurite, and malachite, float poorly with sulfhydryl collectors due to a combination of collector loss through precipitation by heavy metal ions dissolved from the mineral lattice, and collector coatings that are weakly anchored and readily removed by particle abrasion (Fuerstenau et al.,

Oxidized zone minerals | Wat on Earth | University of Waterloo

Peter Russell The oxidized zone of ore deposits has fascinated me for many years because of the process of their formation and the resulting reddish brown rocks. The colourful rocks are a signal to prospectors that economic ore cannot be far away. Stories abound of rusty outcrops luring prospectors across the southwestern U.S.A. to grub in the rocks to find a fortune, or a

Mining and Extraction: Oxide Ores - processes for ...

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Oxidative Hydrometallurgy of Sulphide Minerals - IntechOpen

Sulphide minerals, as pyrite, FeS2, chalcopyrite and CuFeS2, are one of the most important sources of value metals, such as gold, silver, coppe r, zinc, etc. Due to the strong sulfur binding to these minerals, metals are usually extracted by metallurgical process of chemical oxidation.
