Copper Ore Reduction With Carbon

Sales Inquiry

  • Carbothermal Reduction - an overview | ScienceDirect Topics

    One of the merits of the direct reduction with carbon is that the slag is in molten state to react with carbon. In this way, the latent and sensible heat can be utilized, and the contact of carbon with the oxides is much better than that with the solid slag particles. . and a reduction of sulfide ore is the process of choice, as in the case .

    Nov 01, 2017 · We achieved highly selective electrochemical reduction of CO 2 to C 2 H 4 (faradaic efficiency of 25%) by crystalline copper phthalocyanine (CuPc) supported on carbon black. Remarkably, noncrystalline CuPc generated by treatment of crystalline CuPc with sulfuric acid did not give C 2 H 4 selectively, suggesting that catalyst crystallinity is crucial for the selective conversion of CO 2 to C 2 H 4.
