Letâs face it: Most of us don't give much thought to our pee before we flush it out of sight. But the basic details of your urine -- color, smell, and how often you go -- can give you a hint about whatâs going on inside your body. Pee is your bodyâs liquid waste, mainly made of water, salt, and chemicals called urea and uric acid. Your kidneys make it when they filter toxins and other bad stuff from your blood.
Further refining may be performed using one of two processes. In cementation, the acidic solution of copper is deposited on to scrap iron in an oxidation-reduction reaction. After sufficient amounts of copper have been plated, the copper is further refined using the pyrometallurgical process.
Copper thermite. Copper thermite can be prepared using either copper(I) oxide (Cu2O, red) or copper(II) oxide (CuO, black). The burn rate tends to be very fast and the melting point of copper is relatively low so the reaction produces a significant amount of molten copper in a very short time.
