Copper Smelting Process Brighthub Engineering
Historically, copper bearing ores contain only about % copper, the remainder being gangues or unwanted minerals. Chalcopyrite ore is in this range and can be mined by underground or surface methods. After extraction the ore is crushed and screened before being concentrated by a flotation process.

Smelting Wikipedia
Smelting is a form of extractive metallurgy; its main use is to produce a base metal from its ore. This includes production of silver, iron, copper and other base metals from their ores. Smelting makes use of heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving just the metal base behind.

Mining and Extraction Oxide Ores Copper
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
