copper ore granularity

  • Kinetic process of oxidative leaching of chalcopyrite

    At the first stage, the smaller the ore granularity, the faster the copper leaching rate After oxidized for 20 min, the 420 61 "74 ym 5361 um 4453 um 3844 urn QIU Tingsheng, et al/Trans Nonferrous Met Soc China 17(2007) increase with H2SO4 concentration 36 g/L So the increase of H2SO4 concentration can speed up the copper leaching rateCopper ore processing technology: Remarks:The production line is mainly based on the actual material size and the customer's requirements for product granularity According to different production site conditions, Dewo engineers can provide customers with process planning and technical support, and we can also design nonstandard according toCopper ore processing Dewo MachineryAbstract: Process mineralogy research of a mixed copper ore is studied to identify the occurrence mode of copper and to analyze the mineralogical factors influencing the floatation results The results show that the ore has features of "highsulfur, high copper", "various copper mineral types", "fine copper mineral granularity" "disorderlyProcess Mineralogy Study of a Refractory Mixed Copper

  • Mineralogical characterization of copper sulfide tailings

    As ore grades constantly decline, more copper tailings, which still contain a considerable amount of unrecovered copper, are expected to be produced as a byproduct of froth flotation This research reveals the occurrence mechanism of copper minerals in typical copper sulfide tailings using quantitative mineral liberation analysis (MLA) integrated with scanningcopper ore, the wet process for extracting copper from low grade copper oxide is applied widely[1] Direct core sample granularity was 0200−0125 mm, agitation rate was 400 r/min, and mass ratio of liquid to solid was 20׃1, the influence of leachingTechnological conditions and kinetics of leaching copperCopper Ore / Concentrates Both Sulfite Copper and Oxide Copper are acceptable Demand: 300,000 tn per year or above Main destination port: Tianjing Port, Zhoushan Port,Fangcheng Port in China Copper ores: Cu>8% Copper Concentrates: Cu>18% Impurities: As: =<0,5% Bi + Sb: =<05% Pb + Zn: =<8% MgO: =<2% Cl: =<01% F: =<01% No PenaltyOPPORTUNITY ONLY FOR 48 HOURS COPPER MINERAL IS

  • Control method of chalcopyrite passivation in bioleaching

    It occurs in various copper deposits [1−3] Recently, the technique of copper bioleaching has been developed rapidly due to its advantages such as short flow, simple operation, low investment and friendly environment [4,5], which breaks a new way for green exploitation of copper oreAbstract: Process mineralogy research of a mixed copper ore is studied to identify the occurrence mode of copper and to analyze the mineralogical factors influencing the floatation results The results show that the ore has features of "highsulfur, high copper", "various copper mineral types", "fine copper mineral granularity" "disorderlyProcess Mineralogy Study of a Refractory Mixed CopperCopper ore is the main mineral for the large deposits Copper minerals are mostly consisting of chalcopyrite, secondly consisting of bornite, there are traces of processing copper blue and malachite, the mineral is disseminated by coarse granularity This mineral is easy to processing Production process was using by the process of grindingflotationRecovery Copper from a Complex Copper Sulfide Ore of
