The earliest known cast lead beads were found in the Çatal Höyük site in Anatolia , and dated from about 6500 BC, but the metal may have been known earlier. Ancient smelting was done using loads of lead ore and charcoal in outdoor hearths and furnaces. Although lead is a common metal, its discovery had relatively little impact in the ancient world. It is too soft to be used for weapons ...

Zinc Part 1 - History, Deposits, and Production

Near the mines in which zinc ore is extracted in underground or open-cast operations, some plants enrich the zinc content of the ore (5 to 15 %) to about 55 % in so-called concentrates. The separated rock with low zinc content remains in place. In this way, less material has to be transported, which means that less energy is used for transport and zinc extraction is more environmentally friendly.

ABB Mine Hoisting System at Pyhäsalmi Mine

Mining Ltd) discovered the zinc/ copper ore deposit with reserves of over 30 million tonnes in 1958. Open-cast mining started in 1962 and continued until 1976, when it was switched over to underground mining. ABB supplied the mine hoist system. The shaft depth was then only about 660 metres but was later extended to 1,000 metres. In the early 1990s, when the origi-nal reserves were nearing ...

Mining in Cornwall and Devon - Wikipedia

The intrusion of granite into the surrounding sedimentary rocks gave rise to extensive metamorphism and mineralisation. As a result, Cornwall was one of the most important mining areas in Europe until the early 20th century. It is thought that tin ore (cassiterite) was mined in Cornwall as early as the Bronze Age.[citation needed] Over the years, many other metals (e.g. lead and zinc) have ...
