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.

Most copper occurs in ores in igneous (volcanic) rock and sedimentary rock. To process copper commercial, the copper is first extracted from its ores through smelting and is then put through electrodeposition from sulfate solutions. Copper is the thirdmostconsumed industrial metal in the world behind iron and aluminum.

Extracting copper from other ores. Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

Ore grades and mining

Ore grades and mining

+

The grade of an ore is the concentration of the desired material within the rock. There is more metal (a higher concentration) in higher grade metal ores. Ore grades are often given in percentages or in units of ppm. The cutoff grade of an ore is essentially the lowest grade of an ore that is worth mining.

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purifiion, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
