Gold of either % or % purity can be produced from intermediate process products having a wide range of gold contents. The process comprises oxidative leaching of the solid feed, followed by selective solvent extraction of the gold from the leach liquor to reject impurities, and precipitation of highpurity gold powder. This paper outlines the process, presents

Earth's Finite Resources and Human Extraction. For example, polyvinyl chloride (PVC), which is used to make plumbing pipes, contains chlorine atoms. Teflon, used as a nonstick surface on the inside of cooking pans, is formed when fluorine is added to the carbon chain matrix.
This method is used for emerald extraction in Colombia. Tunnel Mining. Some emeralds are harvested through tunnel mining, which involves digging a tunnel through the earth's surface to a vein of emeraldbearing rock. These tunnels can be very small–large enough to fit just one person and a pickaxe. Or they can accommodate larger equipment.
