2. Mining Methods Copper

Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface. Underground mining is used when the copper ore is not near the earth's surface.

Copper mining. From ore to copper. SchoolScience.co.uk

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue).

The mineralogy of Copper Mindat Mines, Minerals

Most widespread minerals containing Copper This list of minerals containing Copper is built from the mindat locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Copper mineral species.

Mining in the United Kingdom

Brief history. The United Kingdom has a rich history of mining. Mining of non-ferrous minerals, particularly of copper and tin, has been ongoing since the Bronze Age. For example, copper was mined in Wales during approximately 2200–850 BC. Metalworking debris found beneath the ramparts at Beeston Castle in Cheshire is evidence of bronze production during the Bronze Age.

There are around 370 commercial copper alloy designations with C106 being the most common with over 18M tonnes consumed each year. Unlike many other metals, the yield strength of copper cannot be easily defined. The most uniform way to work it out is as 0.5% extension under load or as 0.2% offset. Usually the 0.5% extension yield strength of annealed copper is around 1/3 of the tensile
