Copper processing
In the electrolytic process, copper anodes and starting sheets are immersed in an electrolytic solution made up of copper sulfate and sulfuric acid. An electric current is passed through the solution, and copper from the positively charged anode is deposited in a pure form on the negatively charged starting sheet, which acts as a cathode.
Copper Smelting and Refining Process | Pan Pacific Copper
After electrostatic precipitators remove dust particles in the gases, the gas is transferred to the sulfuric acid plant. At the sulfuric acid plant, the catalytic reaction of vanadium oxides causes SO 2 to oxidize into SO 3, which is absorbed in water to yield concentrated sulfuric acid. The manufactured concentrated sulfuric acid and oleum is ...
