Ore is a deposit in Earth's crust of one or more valuable minerals.The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction. . It is a …







Did you know that gold is extraterrestrial? Instead of arising from our planet's rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic stellar explosions called supernovae. CERN Scientist David Lunney outlines the incredible journey of gold from space to Earth.



It's believed that the neutron star collisions and supernovae formed around the time of the birth of planet Earth are responsible for all the gold found on our planet. In other words, the atomic processes of fission, fusion, radioactive decay, gamma-ray burst, etc., resulted in the creation of gold.



We'll explain how silver is made from its formation in the earth to how it's refined. How Silver Forms In The Earth. Silver is formed from sulfur compounds within the earth where its crust heats up to between 200- and 400-degrees Fahrenheit. In nature, silver is found combined with other metals, or in minerals with silver compounds.



Gold is not formed on the Earth like diamonds and many other gems and minerals. Instead, most scientists now believe that gold actually came to earth from outer space in large meteorites that have struck the planet over billions of years. In fact, most of the gold on Earth is actually located in its core where its heavy properties caused it to ...









It flocculates to form a jelly-like substance, which gets trapped in cracks in Earth's crust to form rich gold veins. This finding suggests that rich gold deposits may be more common than we thought, and may have occurred in several other contexts than previous estimates had allowed for. If other studies and further examination can back it …





How is Gold Made in the Earth . Even though gold atoms may have come from meteors and played a role in the formation of the Earth, gold deposits took millions of years to form in the geology. The process starts deep under the surface of the Earth, where the elements needed to make gold are subjected to extreme heat and pressure.



The inner rocky planets, including Earth, formed closer to the Sun, while the outer gas giants like Jupiter and Saturn formed farther out, where the solar nebula contained more volatile elements. Understanding the Big Bang Theory and the formation of the solar system not only deepens our appreciation of the vast cosmos but also sheds …



In Earth's Beginning At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma . Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.





Where to Find Gold. Throughout history, 212,582 tonnes of gold have been mined, with around two-thirds of this amount having been mined since 1950. This staggering amount underscores the relentless human pursuit to uncover this precious metal. But gold's presence on Earth isn't random; it's found in specific places where geological …



How is Gold Formed? First it's important to make a distinction here. Gold isn't actually formed per se. On Earth, gold exists as it is, deep in the earth, though the form it takes (solid, or molten) may differ. There are no naturally occurring processes that produce new gold… on Earth. The process by which gold is created takes place ...





















Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.



















I read theories that gold was formed from stars going nova after the big bang. Prior to Earth's final formation these now ancient meteors/asteroids deposited gold all over the world. Gold would be found closet to the Earth's core. As gold is a heavy element and Earth's early stages, naturally more gold would be found closer to the core.
