500ft. below ground, you would use and open pit mine. If more than 500ft. below ground, you would use a mineshaft (Myslick). The next part of the process is the actual mining. Ore is extracted from the Earth and then crushed. 97% of the actual rock mined is waste (Myslik). After mining, the crushed ore is sent to the mill where the ore is crushed even more into a fine powder and "floated". The powder is placed in giant tanks filled with water. Only the valuable material will float, so as the top layer is skimmed off. 12,000 gallons of water are used per minute for milling (Myslik). The final parts of the process are smelting and refining. The finished product is then sold to consumers who manufacture it for everyday purposes such as jewellery, electronics etc.
