Mining activities are not new and indeed may have started in Neolithic (Chalcolithic) times to obtain the first metals for tool fabrication (Reardon 2011). In the Classic Greece and in the Roman Empire, many mines were exploited for production of iron, lead, copper, gold, and other metals.
The 'Iron Age' | Anglo American
Extracting the metal from the earth is a process that's been refined over the centuries, but essentially it involves mining the rock, separating the ore out by crushing it, and smelting the iron out of the ore by heating it up. After mining, the ore body is crushed and screened into different sizes, which frees some of the ore from the ...

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.
Mining in the United Kingdom - Wikipedia
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.
