Copper sheets are produced by somewhat similar methods of manufacture. In the United States the majority of copper sheets are made from electrolytic copper, but in Europe firerefined copper is used frequently in the manufacture of sheets and plates. Brass. Brass is an alloy consisting mainly if not exclusively of copper and zinc.
How copper is made material, used, processing, steps
The Manufacturing. Process. The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Whatever method is used to manufacture copper from its ore, its final purification is by electrolysis (Figure 6). Slabs of impure copper (blister copper), together with thin sheets of pure copper metal or stainless steel or titanium are immersed in a solution of copper(ll) sulfate (0.3 mol dm3) and sulfuric acid (2 mol dm3).
