With New Design Copper Ore Manufacture

With New Design Copper Ore Manufacture. In early modern times, people began mining copper ore. One of the oldest copper mines in existence is the Great Copper Mountain, a mine that operated in Sweden from the 10th century until 1992. That very mine accounted for the production of two-thirds of Europes copper supply through the 17th century.get price

The partners in the project decided to mine lower-grade ores while maintaining the concentrator throughput, thus reducing the impact on per-ton-treated costs. Output was subsequently ramped up again, and during 2004 the mine handled 377Mt of ore and waste and processed 82.4Mt of sulphide ore grading 1.51% cSee more on mining-technology[PDF]

Innovations: Introduction to Copper: Mining & Extraction

However, by far the greatest extension in the use of copper resulted from Michael Faraday's discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity. The same principle was used to develop electric motors. The electric lamp was invented by Sir Joseph Swan in 1860 and brought to a commercial design by Thomas Edison in 1879.get price
