Tin is a chemical element; it has symbol Sn (from Latin stannum) ... [63] and in 2009, new deposits of tin were discovered in Colombia. [64] Production
Tin is an essential metal in the creation of tin-bronzes, and its acquisition was an important part of ancient cultures from the Bronze Age onward. Its use began in the Middle East and the Balkans around 3000 BC.
The earliest gold artifacts were discovered at the site of Wadi Qana in the Levant. [13] Silver is estimated to have been discovered in Asia Minor shortly after copper and gold. [14] There is evidence that iron was known from before 5000 BC. [15] The oldest known iron objects used by humans are some beads of meteoric iron, made in Egypt in ...
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 [2] 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 ...
Large tin deposits were further discovered in 1823 at the neighboring island of Belitung, and Billiton Maatschappij (today part of BHP) was founded to exploit Belitung's tin, obtaining a concession over the island's mineral rights in 1860.
James (Philosopher) Smith (1 July 1827 – 15 June 1897) [1] was a politician, goldminer, explorer and discoverer of tin reserves in Tasmania, Australia including the Mount Bischoff mine. Smith was born at Georgetown , Van Diemen's Land (now Tasmania ), second of three children of John Smith and his wife Ann, née Grant. [ 1 ]
Tin is one of the earliest metals to have been exploited in Britain. Chalcolithic metal workers discovered that by putting a small proportion of tin (5 – 20%) in molten copper, the alloy bronze was produced. The alloy is harder than copper.
In addition, twenty-nine unstable tin isotopes are known, including tin-100 (100 Sn) (discovered in 1994) [4] and tin-132 (132 Sn), which are both "doubly magic". The longest-lived tin radioisotope is tin-126 (126 Sn), with a half-life of 230,000 years. The other 28 radioisotopes have half-lives of less than a year.
