  • Cu Ore Concentration Process

    Cu Ore Concentration Process. Hot Products. Copper Ore Processing Methods. 2021-1-16 · The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the

  • Copper Wikipedia

    The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). Conversely, the average concentration of copper in polymetallic nodules is estimated at 1.3%.

Le cuivre réagit en présence d’une association d’oxygène et d’acide chlorhydrique pour former toute une série de chlorures de cuivre.

  • 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.

    Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allow it to form froth and Froth Stabilizers (cresols, aniline etc) sustain the froth. The oil wets the metal and the water wets the gangue. Paddles and air constantly

    The results showed that Cu ore deposit mostly was distributed at the altitude of about 630 m. Elsholtzia splendens and Rumex acetosa were distributed only on the Cu ore deposit or the place with high Cu concentration, and the maximum Cu concentrations in these two plants were 1060 mg.kg-1 DW and 1006 mg.kg-1 DW, which reached the critical of hyperaccumulator.
