Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Copper Mineral Uses and Properties

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Copper's metallic luster attracted people's attention. Today most copper is produced from sulfide ores.

The ore is then ground finely before the copper-bearing sulphide minerals are concentrated by a flotation process that separates the grains of ore mineral from the gangue (waste material). Depending on the type of copper -bearing minerals in the ore and the treatment processes used, the concentrate can contain between 25 and 57% copper.

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.
