He was the ..., in his 1839 book ''Report on the Geology of Cornwall'', it produced copper. This was corroborated by Robert Hunt in his 1857 report the ''Mineral Statistics of the United Kingdom of Great Britain''. Copper was produced until about 1873, in which year its output was 147 tons of medium grade ore. References Hamlets in Cornwall {{Penwith-geo-stub ...

Carn Marth
Carn Marth () is the name of a hill in Cornwall, England, United Kingdom, near Redruth. It is high, and is well known for the granite quarry, quarried from it in the past. The name of the hill comes from the Cornish language words ''karn'' (cairn) and ''margh'', meaning 'horse'. Geography and history Carn Marth lies southeast of Redruth and is part of the Carnmenellis granite plateau, the 'Carnmenellis Granite', one of several granite plutons in Cornwall that make up part of the Cornubian batholith (see also Geology of Cornwall). In prehistoric times men settled on the uplands as they had many advantages over the more densely vegetated lowlands. From the late Stone Age they have been natural places of refuge; offering easily defended bases and view points over what was the densely wooded landscape of prehistoric Britain. In early modern times they have been perfect sites to mark victories and celebrations, and to host warning beacons of impending attack such as the feared Sp ...

Tin Mining
Tin mining began early in the Bronze Age, as bronze is a copper-tin alloy. Tin is a relatively rare element in the Earth's crust, with approximately 2 ppm (parts per million), compared to iron with 50,000 ppm. History Tin extraction and use can be dated to the beginnings of the Bronze Age around 3000 BC, when it was observed that copper objects formed of polymetallic ores with different metal contents had different physical properties. The earliest bronze objects had tin or arsenic content of less than 2% and are therefore believed to be the result of unintentional alloying due to trace metal content in the copper ore It was soon discovered that the addition of tin or arsenic to copper increased its hardness and made casting much easier, which revolutionized metal working techniques and brought humanity from the Copper Age or Chalcolithic to the Bronze Age around 3000 BC. Early tin exploitation appears to have been centered on placer deposits of cassiterite. The first eviden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry De La Beche
Sir Henry Thomas De la Beche KCB, FRS (10 February 179613 April 1855) was an English geologist and palaeontologist, the first director of the Geological Survey of Great Britain, who helped pioneer early geological survey methods. He was the first President of the Palaeontographical Society. He was also a slave plantation owner in Jamaica. Biography De la Beche was born in Welbeck Street, Cavendish Square, London. He was the only son of Thomas De la Beche (1755–1801) and his wife, Elizabeth. The family name was originally Beach, but his father changed it to create a fictional connection with the medieval Barons De la Beche of Aldworth, Berkshire. Thomas (Henry's father) served as a brevet major (later lieutenant-colonel) in the Norfolk Yeomanry, a regiment of fencibles in the British Army, and his father was a slave owner with an estate in Jamaica. In 1800 the family travelled to the plantation in Jamaica when Thomas inherited the estate and Thomas died there in the fo ...

Robert Hunt (scientist)
Robert Hunt (6 September 1807 – 17 October 1887) was a British mineralogist, as well as an antiquarian, an amateur poet, and an early pioneer of photography. He was born at Devonport, Plymouth and died in London on 17 October 1887. Life and work Early life Hunt's father, a naval officer, drowned while Robert was a youth. Robert began to study in London for the medical profession, but ill-health caused him to return to settle in Cornwall. In 1829, he published ''The Mount’s Bay; a descriptive poem ... and other pieces'' but received little critical or financial success.Alan Pearson, 'Hunt, Robert (1807–1887)’, Oxford Dictionary of National Biography, Oxford University Press, 200 Retrieved 16 Jan 2011/ref> In 1840, Hunt became secretary to the Royal Cornwall Polytechnic Society at Falmouth.

Chalcopyrite
Chalcopyrite ( ) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a Mohs scale, hardness of 3.5 to 4 on the Mohs scale. Its Streak (mineralogy), streak is diagnostic as green-tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides, and sulfates. Associated copper minerals include the sulfides bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu2O). It is rarely found in association with native copper. Chalcopyrite is a conductor of electricity. Copper can be extracted from chalcopyrite ore using various methods. The two predominant methods are pyrometallurgy and hydrometallurgy, the former being the most commercially viable. Etymology The name chalcopyrite comes from the Greek words , which means cop ...
