China’s kaolin occurrences are widespread in 21 provinces (autonomous regions). The distribution of 101 large (including superlarge) and medium-sized occurrences with known retained reserves is shown in Fig. 4.22.1. Nearly 70% retained reserves are concentrated in Jiangsu, Fujian, Guangdong, Hainan and Guangxi along the southeast coast of China, as well as Jiangxi and Hunan; Inner […]

Kaolin deposits of China may be divided into three types: weathering type, hydrothermal alteration type and sedimentary type, and each type may be further divided into two subtypes. All types and subtypes have their own characteristics in respect to the temporal-spatial distribution and metallogeny. (1) Weathering residual subtype kaolin deposits Kaolin deposits of this subtype […]

The quality of China’s kaolin is generally better than intermediate. According to the statistics of 213 kaolin occurrences (whose retained reserves account for 73% of the country’s total), 72 occurrences (including large or superlarge deposits such as the Yanshan deposit at Suzhou City, Jiangsu, the Donggongxia deposit at Longyan City, Fujian, the Shange and Shangdong […]

Talcum is a mineral of hydrous magnesian silicate with a sheet structure. It has relatively high insulation and thermoinsulation properties, high melting point and strong oil-adsorbing performance. It is mainly applied as a filler, coating in papermaking industry and pulp pitch-controlling agent. And then it can be used for filling materials in roofing products (asphalt […]

Talc is one of the advantagerous mineral resources of China. More than 120 mineral occurrences were discovered. The reserves are abundant. Up to the end of 1997,45 occurrences (8 large, 18 medium-sized, 19 small) with retained reserves have been explored. The retained talc ore reserves of categories B+C+D grades amounted to 250.48 million tons, and […]
