The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Chalcopyrite, bornite, chalcocite, and native copper (an uncombined form of copper) are four minerals often mined for their copper content. Chalcopyrite is the most abundant copper-rich mineral.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

In this article, we'll give a brief overview of rocks that contain copper, why they contain copper, and where you can find these rocks. 6 Rocks That Contain Copper Chalcopyrite. The first rock we'll cover in this article is chalcopyrite, which is one of the major ores of copper. It is found most often in veins of sulfide and igneous rocks.
This calculator provides the calculation of the amount of copper in an ore sample. Explanation. Calculation Example: ... If the total metal content is 7.5%, what is the percentage of other metals present? A sample of copper ore has a density of 3.8 g/cm^3 and a volume of 250 cm^3. If it contains 12.5% Cu, how many grams of copper are in the sample?
Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal in the world.
