How copper is made - material, used, processing, steps ...
The first mention of the systematic extraction of copper ore comes from about 3800 B.C. when an Egyptian reference describes mining operations on the Sinai Peninsula. In about 3000 B.C., large deposits of copper ore were found on the island of Cyprus in the Mediterranean Sea.
Copper Mining and Extraction: Oxide Ores
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing 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.

The mining process begins with extraction of the ore from the ground. The ore then goes through smeltering and converting and the process ends with the refined ore being made into copper plates ready for sale to the world market (Figure 1) (2,3,4).
Copper Mining & Extraction Process Flow Chart
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).

Following open pit extraction of ore, the ore is crushed and transported to a leach pad where it is irrigated with a leach solution to dissolve the metal. This image shows surface pools where dissolved copper is extracted from the solution.

The primary crusher at a copper mine. The truck dumps ore into the crusher which crushes the ore. Screens size and distribute the classified ore to a series of conveyors, like those above, for transportation to the mill for further processing.
USGS Minerals Information: Copper
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
Copper Mining and Processing: Life Cycle of a Mine | Superfund
An ore reserve is the part of the mineral resource that can be economically profitable to mine (i.e., there is enough valuable metal to be worth removing it and extracting it from all of the surrounding rock). After a deposit has been identified as an inferred, indicated, or measured mineral resource, it is next labeled as a "probable" or ...
copper processing | Definition, History, & Facts |
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and ...
Innovations: Introduction to Copper: Mining & Extraction
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Copper is found in the earth's crust and the oceans although the amount in the latter is thought to be negligible, amounting to no more than about eight months ...
