The first tin alloy used on a large scale was bronze, made of 1 ... [63] and in 2009, new deposits of tin were discovered in Colombia. [64] Production
It has been claimed that tin was first mined in Europe around 2500 BC in the Erzgebirge, and knowledge of tin bronze and tin extraction techniques spread from there to Brittany and Cornwall around 2000 BC and from northwestern Europe to northwestern Spain and Portugal around the same time. [19]
The first elemental metal with a clearly identifiable discoverer is cobalt, discovered in 1735 by Georg Brandt, by which time the Scientific Revolution was in full swing. [6] (Even then, cobalt might have been prepared before the 13th century by alchemists roasting and reducing its ore, but,in any case, its distinct nature was not recognised.) [7]
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 ...
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.
On 4 December 1871 Smith discovered a large deposit of tin oxide near the summit of Mount Bischoff. [1] His specimens when smelted yielded the first tin found in Tasmania, but it took some time for the importance of the find to be realised.
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.
The two discovered a new element in a molybdenum sample that was used in a cyclotron, the first element to be discovered by synthesis. It had been predicted by Mendeleev in 1871 as eka-manganese. [171] [172] [173] In 1952, Paul W. Merrill found its spectral lines in S-type red giants. [174]
