Around A.D., tin mines in Britain were important resources in Europe and were used as currency.

17- 19 th century, a large number of tin mines were mined in southeast Asia, which was an important trade project at that time.

At the end of 19, several things affected the price of tin ore:

1. The major tin mines in Southeast Asia were colonized by Britain or controlled by British companies, such as those in Malaya and Indonesia.

2. The non-ferrous metal futures market was established in London, England, which effectively controlled the trading price of tin mines.

3. With the deepening of the industrial revolution, tin has been widely used in industry, and tinplate, tin welding and other war-related applications have made tin a strategic resource.

4. The war clouds in industrialized countries in Europe are getting thicker and thicker, and the demand and hoarding of non-ferrous metals are paid more attention to.

Therefore, from the second half of19th century to the end of World War II, it was the golden age of tin mining.
