The main reason are a relative increase in low-grade tin ore and a lack of large-scale mining operation. Tin deposits in Southeast Asia are, however, also accompanied with various kinds of useful minerals, such as ilmenite, zircon, monazite and xenotime, which have not been fully exploited. Efforts should be made to recover these minerals besides discovering new tin deposits, because extraction of these accessory minerals will, at the same time, result in an increase in the production of tin. In this paper the occurrence, aggregates and chemical composition of these minerals are discussed.
