WCopper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
WCopper is one of the world's most important industrial minerals, and Africa is an important world producer. While output is traditionally dominated by Zambia, South Africa and Katanga Province in the south of the Democratic Republic of the Congo, many African nations contribute to copper production, and many African nations have undeveloped ore resources.
WApliki is a small village in the Nicosia District of Cyprus, located 2.5km North-East of Palaichori Oreinis and is at an altitude of 720 meters above sea level.
WA bal maiden, from the Cornish language bal, a mine, and the English "maiden", a young or unmarried woman, was a female manual labourer working in the mining industries of Cornwall and western Devon, at the south-western extremity of Great Britain. The term has been in use since at least the early 18th century. At least 55,000 women and girls worked as bal maidens, and the actual number is likely to have been much higher.
WCopperbelt Province is a province in Zambia which covers the mineral-rich Copperbelt, and farming and bush areas to the south. It was the backbone of the Northern Rhodesian economy during British colonial rule and fuelled the hopes of the immediate post-independence period, but its economic importance was severely damaged by a crash in global copper prices in 1973. The province adjoins Katanga province of the Democratic Republic of the Congo, which is similarly mineral-rich.
WThe IsaKidd Technology is a copper electrorefining and electrowinning technology that was developed independently by Copper Refineries Proprietary Limited (“CRL”), a Townsville, Queensland subsidiary of MIM Holdings Limited, and at the Falconbridge Limited (“Falconbridge”) now-dismantled Kidd Creek refinery that was at Timmins, Ontario. It is based around the use of reusable cathode starter sheets for copper electrorefining and the automated stripping of the deposited “cathode copper” from them.
WThe Mount Polley mine is a Canadian gold and copper mine located in British Columbia near the towns of Williams Lake, and Likely. It consists of two open-pit sites with an underground mining component and is owned and operated by the Mount Polley Mining Corporation, a wholly owned subsidiary of Imperial Metals. In 2013, the mine produced an output of 38,501,165 pounds (17,463,835 kg) of copper, 45,823 ounces of gold, and 123,999 of silver. The mill commenced operations in 1997 and has a current mine life to 2026. The mining company owns 20,113 hectares (201.13 km2) of property near Quesnel Lake and Polley Lake where it has mining leases and operations on 2,007 hectares (20.07 km2) and mineral claims on 18,106 hectares (181.06 km2). The processed ore is delivered by truck to the Port of Vancouver. The mine is on care and maintenance status until the price of gold, copper, and silver becomes more economically viable.
WThe New Afton mine is a Canadian gold and copper mine located 17 kilometres (11 mi) west of the city of Kamloops in British Columbia. The mine is underground and is owned and operated by New Gold Inc. In 2019, the mine produced an output of 79,000,000 pounds (36,000,000 kg) of copper, and 69,000 ounces of gold. The Afton Group covers 61 claims on 12,450 hectares (124.5 km2) of property.
