The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
Copper Production: How Is Copper Made?
Manufacturing Process of Copper. Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.
Copper Ore – Minecraft Wiki
Copper ore can replace stone, andesite, diorite, granite, tuff, and deepslate. Copper ore that replaces tuff or deepslate becomes deepslate copper ore. It can also spawn rare ore veins above Y=0, mixed with granite and the occasional raw copper blocks. In dripstone caves biomes, copper ore veins are larger on average.

Geology of Copper | Properties, Mining, and Formation of Copper
Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
Copper | Geoscience Australia
The alloy 'cupronickel', a mixture of 75% copper and 25% nickel, is used for making 'silver' coins such as the Australian 5, 10, 20 and 50 cent pieces.
