Innovations: Introduction to Copper: Mining and Extraction

Copper is found in the earth& 39;s crust and the oceans although the amount in the latter is thought to be negligible amounting to no more than about eight months mine production at present-day rates. The upper 10 kilometers of the crust is thought to contain an average of about 33 ppm of copper. For commercial exploitation copper deposits generally need to be in excess of 0.5% copper and

How copper is made - How Products Are Made

Despite this early production most copper used in the United States was imported from Chile until 1844 when mining of large deposits of high-grade copper ore around Lake Superior began. The development of more efficient processing techniques in the late-1800s allowed the mining of lower-grade copper ores from huge open-pit mines in the western United States.
