Experimental process 1. Prepare lengths of copper wire, 6 to 10 inches long, or tubing, 1 to 1.5 ft in length. 2. Ask selected class members to slowly bend the copper—careful not to cause crimping. 3. Once bent, ask another class member to unbend the copper. 4. Discuss why the copper cannot be fully unbent due to work hardening. 5.
What Is Copper Smelting? (with pictures) - Info Bloom
Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
