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.
At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite-CuFeS2. From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.t this stage of the process, the chemical reactions begin.
