What is Tin?

Tin is a metal that has been used since antiquity. It is an essential component of many modern technologies, including plumbing and electrical wiring. Tin also has military applications, such as in the construction of armour and firearms.

Tin is a chemical element with the symbol Sn and the atomic number 50. It is a silvery-white, malleable metal. Tin is not radioactive. It is soft, malleable, ductile and highly corrosion-resistant. Tin is one of the least abundant ( 49th most abundant element in Earth’s crust) ,and most widely distributed of the elements. It occurs naturally on Earth in three relatively stable isotopic forms: as an oxide (SnO2), a sulfide (SnS) and a chloride (SnCl).

How was Tin first discovered and used?

The history of tin goes back alongside the history of mankind, so its exact discovery cannot be dated. But we know that 3000 years ago, bronze was made with 1/8 tin and 7/8 copper. Pewter, which is an alloy of 85–90% tin, has been used for flatware since the Bronze Age.

Here in Britain we have been mining tin for a long time. Tin mining started in prehistoric times and went on through Bronze Age Britain. There were a lot of Classical writers who talked about tin mines in Britain. South-West Britain was one of the few places in Anglian stage England that didn’t get hit by glaciers and tin ore was easy to find on the ground. In the beginning, it is possible that cassiterite alluvial deposits in the gravels of streams were mined. Later, underground mining took place. Then, shallow cuttings were used to get the ore. In the 19th century, improvements in mining engineering made it possible to mine much deeper than before. In a few places, these mines even went down to multiple levels and worked under the seabed.

Cornwall and Devon provided most of our tin, copper, and arsenic until the 20th century. As a result the landscape, particularly in Cornwall, is covered with the remnants of mines and their associated processing works. Some of the most famous of these are at Wheal Coates and Botallack. They are well worth a visit.

Currently the top 3 producers of tin are:

• China,
• Indonesia
• Peru.

What are some common applications for Tin?

Tin is a metallic element that has several important applications in industry. The most popular use of tin is in cans and other food packaging. Tin also has important military and aerospace uses.

Some common applications for tin are:

• Solder. Tin is used in tin/lead soft solders that are 60% or more tin and in the production of transparent. Around half of all tin is used in solder each year. Therefore it is found in PCBs, the scourge of e-waste.
• Specialised alloys such as pewter, bronze, bell metal and, in modern science in niobium as part of superconducting magnets
• Church organs
• Optoelectronics alongside iridium
• Food cans as tin plated steel.
• Li-Ion batteries.
• Recycling: How is Tin recycled?

Tin can be reused over and over again because of its inherent properties and value to the economy. And as you will know as a visitor to this website, closing metal loops by reusing and recycling more can improve resource productivity while cutting down on energy use, emissions, and waste disposal. That is after all why you are a scrapper.

As you can see tin is not found on its own in our waste, rather as an alloy. Therefore there is no use for the microscrapper to try to salvage tin individually. But by passing on PCBs and tin cans to refiners you are helping recover tin anyway.

Conclusion: What is the future of Tin?

Despite its many limitations, tin is still an important and widely used material in modern technology. Over the next few decades, there are several potential developments that could increase tin’s usefulness even more. For example, scientists are working on new ways to use tin as a conductor of electricity and as a catalyst for chemical reactions. Additionally, advances in manufacturing technologies may make it easier to produce tin products using less of the metal. As a result, the future of tin looks promising and may continue to play an important role in technological innovation for years to come.
