Copper Mining and Extraction Sulfide Ores

Copper is an unreactive metal, it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. The largest nugget of native copper ever found came from Minnesota,

Innovations: How Do They Do That? How Copper is Made

2021-8-12  Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.

2016-9-26  Pure Copper Is Rare, But Copper Ores Are Abundant As mentioned, pure copper is rare because most of it is naturally combined with other chemicals to form copper ores. The most common copper ores—there are about 15 of them mined in 40 countries— are sulfide ores, where the copper has bonded chemically with sulfur.

How is copper mined and processed? AskingLot

Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.
