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.
When copper is mined it often contains impurities of other mostly heavy metals because of coppers density. To remove the impurities the copper is smelted, which means that it is boiled to a temperature which removes the accessory minerals (this waste product is called slag). This pure copper (sometimes copper is found completely pure in veins, but that is rare,) is then sold to industrial manufacturers and others.
