Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.
Copper is one of the first metals to be used, largely because it occurs in metallic form at the surface. By 4000, it was being smelted from ores in Israel and other parts of the Middle East. Copper is a malleable, ductile reddish metal, and is one of only two strongly colored metals (gold being the other).

· Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a strip of overburden before mining a seam of mineral. Strip mining is done only when the ore body is in close proximity to the surface. Openpit mining – Openpit mining is the method in which minerals or ...
· Some mining machines are used to transport mining or workers (miners), you can also use machinery to introduce explosives with a longitudinal arm making the explosion more effective. Other types of mining machinery are used to introduce the concrete into the wall of the rock making it more consistent and safer. Mining equipment list
Mining of these nodules could result in the destruction of life and the seabed habitat in the mined areas, which has been simulated in the eastern Pacific. Because the CCZ is outside national jurisdiction, deepsea mining in this region is regulated by the International Seabed Authority .
The Philippines considered as one of the countries most endowed with metallic resources in the world, ranks in the top 6 for gold, nickel, copper and chromite and has the potential to be top 10 largest mining power in the world.

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 mostused metal in the world.
· However, certain other methods have been around for millennia and have not yet lost their efficacy. Certain metals like copper and silver were the preferred antimicrobial method of Hippocrates in the fourth century, according to the Deccan Herald. Persian rulers used similar techniques to eliminate bacteria from food and water.
· Mining for metal ores involves quarries. which ... Certain bacteria. can break down lowgrade ores to produce ... Since iron is cheaper than copper, the use of .
copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or openpit mining, is the predominant mining method for copper in the world. After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical.
After the recovery period, the benefits are shared 50%/50% based on the net mining revenue, inclusive of taxes; • Investors can also avail of the incentives under the Special Economic Zone Act of 1994 if they will engage in downstream processing and be entitled to exemptions from certain national and local taxes. Under the Mining Act
