The copper bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning SX EW. Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro chemical deposition.
Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide silica, calcium carbonate CaCO 3 and air in a furnace. The major steps in the extraction of copper are Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
The successful development of the Cyprus Copper Process has been an evolutionary series of events covering a time span of some seven years. What does the Cyprus Copper Process do? Very simply, it converts copper concentrates ofposition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper suitable for electrical applications. This
Pure metal is deposited at the cathode. The electrolyte is made of the metal solution e.g. for copper, it is copper sulphate and for nickel, it is nickel chloride. Energy consumption in copper refining by electrolytic process is 150 to 300 kWH/tonne of refined copper.
Method: copper electrodes Pour copper sulfate solution into a beaker. Measure and record the mass of a piece of copper foil. Attach it to the negative terminal of a DC supply, and dip the copper foil into the copper sulfate solution. Repeat with another piece of copper foil, but this time attach it to the positive terminal. Make sure the electrodes do not touch each other, then turn on the
