Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Occurrence and Mining of Copper. Copper is one of the few metals found in its native elemental state. Elemental copper is found associated with copper ores around the globe, including North America, Africa, Asia, Europe, and South America. Copper and copper ores are commonly found in basaltic rocks, with its most common ore being chalcopyrite

Mining. Copper at CSA mine is extracted through the long hole open stopping (LHOS) method. Underground tunnels and open stopes of 30m height and 10m width are dug. The stopes are blasted and drilled to extract copper. The blasted ore is transported to an underground stockpile in trucks.

In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed.

Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

A method of short-hole mining, cut-and-fill mining is used in irregular or steeply dipping ore zones, especially where the hanging wall limits the use of long-held methods. The ore is mined either in slightly inclined or horizontal slices then it is filled with sand, waste rock, or tailings.

The most viable way to recover the ore body is by a well-established underground mining method called block caving. Block caving is safe, environmentally sound, and cost-effective for mining a large, deep orebody. In block caving, a large section of ore is initially undercut by drilling and blasting, causing it to collapse under its weight.

The people used native copper at first, and experimented with different furnace styles in order to smelt the ore between 2500 and 1500 BCE (Ehret 2002). Copper metallurgy has been recorded at Akjoujt in western Mauritania. The Akjoujt site is later than Agadez, dating back to around 850 BC. There is evidence of mining between 850 and 300 BC.

Once an ore has been probed to be economically viable, and a pre-feasibility study has been conducted to classify the economically viable mineral volume as measured, indicated, and inferred resources, the most appropriate mining method needs to be selected based on the characteristics of the ore, such as dip size, shape of ore body, and strength of ore body.

In 2015, the average copper grade in the ores was only 0.65 %. For the year 2026, it is expected that the ores in Chile will have copper grades of less than 0.5 %. This will naturally increase the amount of run-of-mine ore that has to be processed. In international comparison, the Chilean copper ore mining industry is steadily deteriorating.
