Decopperization mechanism of copper anode slime

Seisko et al. [ 15] investigated the pressure leaching of the copper anode slime and found that copper 65–100%, nickel 57–98%, bismuth 53–82%, arsenic 16–61%, tellurium ≤58% and selenium ≤57% were leached when the temperature was in the range of 80–120 °C. Under O2, the leaching rate of copper is only 41.1% at 90 °C.Join for free.

Potential–pH diagram for Cu–H 2 O system shown in Fig. 11.4 suggests that Cu 2+ reduction reaction Cu 2+ + 2e = Cu has more positive potential than for H 2 evolution reaction and negative potential compared to oxygen reduction. Hence, hydrogen evolution reaction cannot be used as a cathodic process to dissolve copper metal The waste heat recovery is not included in Fig. 1 Schematic process flow diagram of the synergistic copper process [4] the calculations.

Hydrometallurgical Copper Extraction Request PDF

Hydrometallurgical extraction accounts for about 4.5 million tonnes of cathode copper per year (about 20% of total primary copper production). Most of this is produced by heap leaching. HeapThe Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The purification uses an electrolyte of copper(II) sulfate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell.

[Show full abstract] 33, and its hardness was uniformly distributed over the whole.(2) The desirable time for process annealing of the copper clad aluminum wire should be less than 1hr at 250°CThe remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.Copper Production: How Is Copper Made? ThoughtCo

Phase diagram for the Cu-S system (Shishin and Decterov

In this study, the copper smelting process has been modelled using a mass and energy balance [13] implemented with equations for coefficient distribution parameters of copper, lead, and zinc.The success of composite extrusion is influenced by multiple process parameters. In order to investigate the significance of specific parameters during indirect extrusion of copper-clad aluminum (CCA) rods, statistical methods were applied and a central composite experimental design was implemented.
