dissolve copper sulphate in dil. sulphuric acid. Place two metal plates(Cu and Pt) pass DC current between the plates (electrodes). Fix the negative pole of the DC source to copper and positive pole to platinum. Copper deposit on copper and you are end up with copper metal which can be reused. The solution finally is free of copper sulphate

Copper ore (typically Copper Sulfide) is roasted in a Smelter furnace. Oxygen in the air burns off the Sulfur, leaving the metallic Copper in the furnace, making a mixture of Sulfur Dioxide & Sulfur Trioxide in the stack gasses. This, combined with rain water makes a mixture of Sulfurous Acid & Sulfuric Acid, aka acid rain. The EPA now requires Smelters to put scrubbers on their stacks to capture these gasses and prevent acid rain.The Copper is further purified by casting it into to plates, which are put into a bath of Copper Sulfate and electrolytically plating the Copper onto another set of Copper plates. Contaminates in the plates cast directly from the molten Copper in the furnace settle out to the bottom of the Copper Sulfate bath tank.
Plates for printing handbills and copper was used in pots and pan bottoms. It still is today in the Revere pot and pan line of products. Copper is a good conductor of heat.
