Previous Year Question
In Malaysia, the ‘Kinta Valley’ is famous for
Rubber Production
Tea Production
Tin Production
Coffee Production
Correct Answer: C
Detailed Solution
The Kinta Valley is located in the State of Perak, Malaysia, and has historically been world-famous for tin mining. An official document of Malaysia's Inland Revenue Board explicitly refers to the tin-mining industry in the Perak Kinta Valley area.
The principal ore of tin in the Kinta region is Cassiterite (SnO₂). Much of the tin has historically been recovered from alluvial deposits. Concentration of heavy cassiterite grains in sediments transported by rivers contributed to the development of extensive placer deposits.
According to the Bulletin of the Geological Society of Malaysia, associated with Malaysia's higher-education research system, the Kinta Valley had been one of the world's largest and most productive tinfields since 1890, contributing about 30% of Malaysia's recorded tin production. Alluvial tin was extensively recovered by dredging and gravel-pump methods.
