Gold has been used to make ornamental objects and jewelry for thousands of years. Gold nuggets found in a stream are very easy to work and were probably one of the first metals used by humans. Special properties of gold make it perfect for manufacturing jewelry. These include very high luster, desirable yellow color, and tarnish resistance ability to be drawn into wires, hammered into sheets or cast into shapes.

New pollution control technologies can greatly reduce emissions from gold roasters. For ex: according to University of Nevada environmental, science professor Glenn Miler strubbers have helped Nevada cut its mercury emissions from more than 20, 000 pounds a year a decade ago to just about 4, 000 pounds a year. Meanwhile, there’s hope that new treatment processes can also alleviate the serious mercury pollutions issues related to small scale gold-mining in the developing world. Gold particle are very good at capturing X-rays, so if they could be made to penetrate cancer cells from within. “So the fact its gold may be useful”.
