- Africa. African tin mining is concentrated in the DRC, Uganda, Burundi, Rwanda and Nigeria.
- China. China is by far the world’s largest market for tin and also the largest producing country, now accounting for around 40% of world refined tin consumption and production.
- Indonesia.

Which state is famous for tin-mining?
Chhattisgarh is the only tin producing State in India. Tin ore is known as cassiterite, which was reported in Dantewara district (Bastar district in formerly Madhya Pradesh) by the Directorate of Geology and Mining associated with the lepidolite bearing pegmatites.
Where is tin ore found in the US?
The majority of tin occurrences are located in the state of Alaska, but tin is known to occur in many other locations in the contiguous United States. The cassiterite ore originates from various lode deposit types, including greisens, pegmatites, skarns, and veins, as well as from placers sourced from these systems.
Where is the biggest tin mine?
Once the world’s biggest source of tin, the Sungai Lembing (Spear River) mine in the central Malaysian state of Pahang is back in business after two closures–the last in 1987 after the collapse of the global tin market.
How do you purify tin?
Refining
- There are two methods of refining impure tin. Fire refining is most commonly used and produces tin (up to 99.85 percent) suitable for general commercial use.
- One fire-refining method is called boiling.
- Another fire-refining method is liquation.
- Vacuum distillation is sometimes used in fire refining.
Is tin expensive or cheap?
Tin’s price per pound is about 3 to 5 times that of base metals such as zinc, lead, and copper, yet it is much cheaper than precious metals such as silver, gold, and platinum.
How much tin is left in the world?

Is tin mined or made?
Most metallic tin is produced at smelters and refineries located near mining areas.
Can you mine tin?
They are mined by one of several surface-mining methods, principally gravel pumping, dredging, and, to a smaller extent, open-pit mining. A large proportion of tin ore is mined by gravel pumping.
How common is tin?
about 2 parts per million
Tin is a relatively scarce element with an abundance in the earth’s crust of about 2 parts per million (ppm), compared with 94 ppm for zinc, 63 ppm for copper, and 12 ppm for lead. Most of the world’s tin is produced from placer deposits; at least one-half comes from Southeast Asia.
Where is tin mined now?

| Country | Mine production | Smelter production |
|---|---|---|
| Indonesia | 117,500 | 80,933 |
| China | 114,300 | 129,400 |
| Peru | 38,470 | 40,495 |

Why is tin so cheap?
In the past, the instability of this region has led to price spikes in tin. Essentially no tin is mined or smelted in North or Central America. Tin’s price per pound is about 3 to 5 times that of base metals such as zinc, lead, and copper, yet it is much cheaper than precious metals such as silver, gold, and platinum.
Where are the tin ore deposits in Nigeria?
Tin Ore (Sn) Rich Deposits States In Nigeria And Related Information. Tin Ore mineral deposit was discovered in Nigeria, West Africa by Sir William Wallace in the year 1884, who was as of then works with the National African Company. Tin was and is still being produced by the natives of Plateau, Abuja and Bauchi State.
Where does most of the world’s tin come from?
Nearly every continent has an important tin-mining country. Tin is a relatively scarce element with an abundance in the earth’s crust of about 2 parts per million (ppm), compared with 94 ppm for zinc, 63 ppm for copper, and 12 ppm for lead. Most of the world’s tin is produced from placer deposits; at least one-half comes from Southeast Asia.
How is the mining of tin ore easy?
The mining of tin is not as difficult as some of the natural solid minerals, it’s easy because it is mined from the vein containing tin ore. Production of tin is carried out by carbothermic reduction of the oxide ore with carbon or coke.
When did tin mining begin in the Americas?
In Africa, the Bantu culture extracted, smelted and exported tin between the 11th and 15th centuries AD, in the Americas tin exploitation began around 1000 AD, and in Australia it began with the arrival of Europeans in the 18th century. During the Middle Ages, and again in the early 19th century, Cornwall was the major tin producer.
