Natural heavy mineral of placer are usually used to interpret generation, pathways, provenance and even geochemistry of sediments (Inga, et al. 2012; Sergio, et al. 2012). Few studies consider their implication to genetic mineralogy and ore mineralogy, particularly to the tin deposit, such as Lailishan in the Western Yunnan, an important tin belt in China (Cai, 1985). Successfully recognition of natural heavy minerals is a significant way to find out ore deposit. On the one hand, assemblages of typical natural heavy minerals are from ore occurrence area, giving information for origin and genesis of ore. Besides, such characteristics about color, grain size, crystalline shape and rounding as the typomorphic mineral like cassiterite have can provide clues to find potential ore resources.
