Copper - Wikipedia


The development of more efficient processing techniques in the late-1800s allowed the mining of lower-grade copper ores from huge open-pit mines in the western United States. Today, the United States and Chile are the world's top two copper producing countries, followed by Russia, Canada, and China.

ore | National Geographic Society


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.

The Copper Age was a time period between the Neolithic and the Bronze Age.It is also named Chalcolithic (Ancient Greek: χαλκός khalkos "copper" + Ancient Greek: λίθος lithos "stone").. In the Bronze Age, people added tin to copper to make bronze, an alloy which is much harder than either tin or copper. During the Copper Age, this fact became known, but was not much used because tin ...

Smelting - Simple English Wikipedia, the free encyclopedia


Smelting is the general term for getting a metal from its natural ore.Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore.. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.Most ores are oxides, sulfides or carbonates.
