The two most frequent methods of tin mining in Malaysia are alluvial open-cast tin mining (Figs. 8.22 and 8.23) and dredging (Figs. 8.2 and 8.16). Gravel pumps were popular because of their minimum initial investment. The tin mining business has been in sharp decline since the global tin market collapsed in 1985.

Ask the Chatbot a Question Ask the Chatbot a Question placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles.When heavy, stable minerals are freed from their matrix by weathering processes, they are slowly washed downslope into streams that quickly winnow the lighter matrix. Thus the heavy …
