The main resource is cassiterite polymetallic sulfide ore. The primary useful minerals of cassiterite polymetallic sulfide ore are cassiterite, pyrite, pyrrhotite, arsenopyrite, sphalerite, jamesonite, and small amounts of sphalerite, tetrahedrite tin, galena, and chalcopyrite. Gangue minerals are mainly quartz and calcite . This type of tin ore must be comprehensively utilized because of its many associated mineral .
