Cornstarch Replaces Cyanide In Clean New Gold
Gold, precious forever but especially lately, is a tricky metal Bound up in consumer electronics, jewelry and the ores that it comes from, gold is difficult to For example, the production of electronic and electrical products consumed 53% (197 tons) of the world’s gold supply in 2001, and 77% (320 tons) in 2011 Over that same decade, the price per ounce of gold soared by five times, from under $300 to more than $1,500 Yet, globally, less than 15% of the gold in ewaste is recovered for reuseOnly 15% of gold/silver used annually in hightech Recycling of used electronics can yield materials (eg, gold, copper, glass, aluminum) that can be returned to the supply chain to be used again, reducing raw materials used and the overall need for disposal Over time, better and more efficient recycling technologies can be developed EPA encourages electronics Basic Information about Electronics Stewardship How to Test Gold at Home Gold is a precious metal that comes in a variety of colors and different levels of fineness The value of a piece of jewelry or another object will depend greatly on whether or not it is plated or pure gold3 Ways to Test Gold at Home wikiHow Electronics is already playing a huge role in different areas, such as communication, entertainment, security, sports and education It is an exciting time for medical technology, and making smart use of modern digital innovations may bring Electronic Pill: The Holy Grail Of Healthcare Technology
