China’s barite resource ranks first in the world and is concentrated in distribution. The 82th of the identified reserves are distributed in five provinces: Guizhou (34%), Hunan (21 ~ 22%), Guangxi (14%), Gansu (7%), and Shaanxi (6%).
Barite deposits in China are relatively simple and can be divided into three types: sedimentary type hydrothermal type and residual slope type.
- Sedimentary type is the most important deposit type, and the accumulative resource reserves account for 67. 7%. It is mainly concentrated in Cambrian, followed by Devonian, with the advantages of large scale and easy mining.
- The accumulative resource reserves of hydrothermal barite deposits account for 31. 3%. 0, mainly small and medium ore deposits, mainly in Ordovician, Devonian and Triassic, often associated with other minerals.
- The accumulative identified resource reserves of residual slope type barite deposit are only 1.4, and the scale is small, only in Quaternary.
