Copper Purification Process - Electrolytic Copper Refining ...

The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxide and chlorine. In the electrolytic refining of copper, a thin sheet of high-purity Cu serves as the cathode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.

Chapter 6 Copper Production Technology

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
