Tin Mining in Malaysia- Is There any Revival?

HISTORY OF TIN MINING Tin ore has been mined in Malaya for centuries. At that time, mining methods were primitive and tin ores were mined along the river banks. It was the discovery of large deposits of tin ore in Larut, Perak, in 1848 by Long Ja'afar that started the development of the tin mining industry in Malaya. Long Ja'afar

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.

Tin mining - Wikipedia

Tin extraction and use can be dated to the beginnings of the Bronze Age around 3000 BC, when it was observed that copper objects formed of polymetallic ores with different metal contents had different physical properties. 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 ...
