This process is repeated several times, which leads to the segregation of impurities at one end of the rod. Then, the end with the impurities is cut off. Silicon, boron, gallium, indium etc. can be purified by this process. (ii) Electrolytic refining; Electrolytic refining is the process of refining .

Copper Refining Corrosion

Copper Refining Corrosion

Copper Refining. Copper is widely used to make electrical wiring and in other applications that utilize its high electrical conductivity. Crude copper, which is usually obtained by pyrometallurgical methods, is not suitable to serve in electrical applications because impurities greatly reduce the metal's conductivity.

2. In copper processing, a copper cathode is the final, % pure product of the electrolysis process, and is itself the primary raw material input for the production of finished copper products, such as rode, tubes, and wires. copper A reddishbrown, ductile, malleable metallic element that is an excellent conductor of heat and

Copper Mining and Extraction: Sulfide Ores

Copper Mining and Extraction: Sulfide Ores

Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.
