In the paper, the rock and ore are divided into three main classes and five subclasses based on iron grade and data of perforating for production in Main Mine of Bayan Obo in recent years as well as distribution rules and space coupling characteristics of contents of F and S in various types of rock and ore are summarized. The research results showed that the main occurrence minerals of element F in Main Mine of Bayan Obo were fluorite and bastnaesite as well as main occurrence minerals of element S were pyrite, pyrrhotite and galena. In terms of distribution of contents of elements F and S, it generally shows the change rule of “increasing first and then decreasing” with the increase of iron grade of ore; in terms of space distribution, elements F and S are most closely related to iron ore, space distribution range of elements F and S is gradually decreased as well as overlapping area is gradually decreased and separated, which shows the distribution characteristic of “alternate zoning with variants” with the increase of contents of F and S.
