Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
Large stripping machines with excavating wheels used in surface coal mining are employed in other types of openpit mines. Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steamdriven pumps could be used to remove water from the deep mines of the day.
