how were copper deposits formed
How Is Copper Formed?
· How Is Copper Formed? Copper forms as molten rock with small amounts of copper fluid crystallizes. As the larger rock continues to solidify, the fluid rich in copper moves into cracks, eventually solidifying as well. Because the copper solidifies later than other minerals within the larger rock, the final deposits have a high concentration.

Uses of Copper | Supply, Demand, Production, Resources
Copper deposits are broadly classified on the basis of how the deposits formed. Porphyry copper deposits, which are associated with igneous intrusions, yield about twothirds of the world's copper and are therefore the world's most important type of copper deposit.
Earth's copper resources estimated from tectonic diffusion ...
· 11 tonnes (t) of copper. Assuming that other types of copper deposits behave similarly in the crust and have abundances proportional to their current global production yields an estimate of 3 × 10 11 t for total global copper resources at all levels in Earth's crust. Thus, ∼% of the copper in the crust has been concentrated into deposits through Phanerozoic time, and about twothirds of ...

· Copper is all around us: in our homes, electronic devices, and transportation. But before copper ends up in these products and technologies, the industry must mine, refine and transport this copper all over the globe.. Copper's Supply Chain. This infographic comes to us from Trilogy Metals and it outlines copper's supply chain from the mine to the refinery.
How Are Minerals Formed? | Sciencing
· A solid mineral deposit can also be formed from the evaporation of a liquid solution. When a mineral is suspended in a solution, it can collect as the water in the solution evaporates into the air. Examples of mineral deposits formed this way can be found in caves; calcitesaturated groundwater can slowly collect in stalactites and stalagmites over time.

The Ancient History of Copper
· Copper Findings . Although various copper tools and decorative items dating back as early as 9000 BCE have been discovered, archaeological evidence suggests that it was the early Mesopotamians who, around 5000 to 6000 years ago, were the first to fully harness the ability to extract and work with copper.

Gem Formation: How are Gemstones Created?
Traditionally, we were taught that there are three kinds of rock formation processes: Igneous rocks are created with heat, deep within the Earth. Metamorphic rocks form when heat and pressure conditions change existing minerals into something new. Sedimentary rocks form from deposits of sediment.
MAGMATIC DEPOSITS

Chemistry of Copper
· Brass (copper and zinc) and bronze (copper and tin) are two examples. The symbol and name for copper are from the Latin cuprum, which literally means "from the island of Cyprus", an early source of copper ore. Before 1982 pennies were pure copper. Now they are mostly zinc with a thin shell of copper.
