USES: Tin has many uses. Electro-plating is an important application of tin. It can be done through the electroplating of a small coat of tin around objects of steel, copper, aluminum etc. The tinned pieces have countless applications such as in kitchen utensils, spray recipients and shaving , ink cans, electronic components, integrated circuits, clips, pins and many other.
The hope of finding mineral treasure was one of the incentives that led the early colonists to America and they were quite diligent in searching for metals. All along the Atlantic Coast, almost immediately after the first settlements, discoveries were made of silver, lead, copper, iron, tin, antimony, coal, and other valuable minerals; but, they were found generally in small quantities; and ...

The name Wolfram is closely related to today's important tungsten mineral wolframite. In the Middle Ages (16 th century) tin miners in the Saxony-Bohemian Erzgebirge in Germany reported about a mineral which often accompanied tin ore (tinstone). From experience, it was known that the presence of this mineral reduced the tin yield during smelting.
May 01, 2017· In the Middle Ages, tin miners in Germany complained about a mineral (wolframite) that accompanied tin ore and reduced tin yields when smelting. With a longish, hair-like appearance, wolframite was thought to be a "wolf" that ate up the tin.
The history of tin began in 1810. The British Government granted a patent to a merchant, Peter Durand for his idea of using. 1871 AD. James Smith found the rich deposit of tin at Mount Bischoff. The discovery of tin drew the attention of the people to the investigation of the rich mineral resources of the colony.
The only mineral of commercial importance as a source of tin is cassiterite (SnO 2), although small quantities of tin are recovered from complex sulfides such as stannite, cylindrite, franckeite, canfieldite, and teallite. Most tin is used as a protective coating or as an alloy with other metals such as lead or zinc.
The History of Castrol. On 19th March 1899, Charles 'Cheers' Wakefield set up an oil company in England. Ten years later, he produced a new lubricant that would revolutionise transport in the first half of the twentieth century. He called the new oil Castrol. Castrol oil has become synonymous with world speed and endurance records.

Cassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek "kassiteros", meaning tin.
Oct 03, 2017· It was the first Mhuang Soob in Thailand. It needed a large plain, a lot of equipment and a variety of vehicles. Therefore, dikes and rail tracks for the movement of mineral ore were built.

Background. Tin is one of the basic chemical elements. When refined, it is a silvery-white metal known for its resistance to corrosion and its ability to coat other metals. It is most commonly used as a plating on the steel sheets used to form cans for food containers. Tin is also combined with copper to form bronze and with lead to form solder.
