Copper: A Must-Read Resource For Curious Traders In

2021-3-25  Copper is soft, pliable and malleable, and it conducts heat and electricity very well. However, unlike gold and silver, copper is not widely viewed as a store of value. Therefore, copper is less impacted by speculative price movements. The global supply of copper comes principally from underground mines and from recycling copper products.

World Copper Production at a Glance - FEECO

Once mined, copper ore goes through a series of processing stages in order to refine it into a saleable copper product. Copper can be refined by one of two approaches: pyrometallurgy or hydrometallurgy. Pyrometallurgical Copper Refining. The pyrometallurgical approach, often referred to as smelting, is the primary method used for refining copper.
