Abstract:

In Vietnam, hydrothermal‐metasomatic kaolin of the secondary quartzite type is discovered, explored, and exploited along with pyrophyllite, alunite, and high‐alumina quartzite in the northeastern region of Quang Ninh province. Due to the formation characteristics and complex mineral components in ore bodies, this leads to the difficulty for mapping out particular kaolin bodies, and in many cases. Therefore, mineral resources of the kaolin and pyrophyllitic ores are being added together during the explored and exploited process. In reality, the calculation and estimation of kaolin resources/reserves in the kaolin ‐ pyrophyllite ore body not only makes sense in scientific terms, but also the basis for exploitation orientation and processing to ensure rational use of mineral resources. In this paper, a calculated method is provided for estimating kaolin resources in the kaolin ‐ pyrophyllite ore bodies via basic contents. The calculated results show that the kaolin resources reach about 22 million ton and count for more than 14% of total mineral resource of the kaolin ‐ pyrophyllite mine.
