  • Copper extraction Wikipedia

    Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper-in-concentrate

  • Galena Wikipedia

    Galena is the main ore of lead, used since ancient times.Because of its somewhat low melting point, it was easy to liberate by smelting.It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.In these deposits significant amounts of silver occur as included silver sulfide

  • Research on the Role of Pre-Oxidation in the Separation of

    It is the most effective method to use potassium dichromate to separate copper from lead when galena is oxidized. However, it needs long time to oxidize galena by potassium dichromate. The efficiency of five oxidants on potassium dichromate depressing ability to galena have been studied completely in this paper, and results suggest that separation of Cu-Pb can be carried out effectively in
