Extraction European Copper Institute
Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
How can electrolysis be used to purify copper? Socratic
16/02/2014· Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure. It contains traces of metals such as Fe, Zn, Ag, Au, and Pt. The purity can be increased to 99.95 % by electrolytic refining in a cell similar to that shown below. A thin sheet of high-purity Cu serves as the cathode.
Electrolysis
Because impurities can dramatically decrease the conductivity of copper wires, impure copper must be purified. One method of purifying copper is by electrolysis. When a strip of impure metallic copper is used as the anode in the electrolysis of an aqueous preparation of copper(II) sulfate, copper is oxidized. The oxidation of copper is more
