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.
All copper sulfide ores are concentrated using the froth flotation process. Ground ore is mixed with xanthate reagents (for example, pine oil), which reacts with the copper sulfide mineral to make it hydrophobic on its surface. The sulfide ore is crushed and ground to increase the surface area of the ore for subsequent processing.
