Nai is a mixture of generic kaolin mine, belonging to non-metallic mineral
Probably the main chemical components: SiO2 Al2O3 Fe2O3
Different specifications of different resources
Kaolin ore price difference is large, for example: Suzhou, China kaolin ore price is 230 yuan / t, Fujian Longyan Kaolin ore price of 90 yuan / t, Wuxian Castle Nai ores price of 203.5 yuan / t, ore price impact _Select_ mining methods and extraction processes. Guangdong Maoming Kaolin Kaolin is sandy, water mining waterways, mainly produces paper coating grade kaolin, there is no problem of ore to sell its low-end products for the ceramics, fillers used.
