Situation of Boron Resources Holds No Room for Optimism
Most of boron ores in China have a low grade. Boron ores with a boron trioxide content of no more than 12% account for 90.74% of the total reserves and rich ores with a boron trioxide content of no less than 20% only account for 8.54%. More than 95% of mineral raw materials used in the boron industry of China are boromagnesite ores, but boromagnesite ores only account for 6.64% of the total boron ore reserves in China. Paigeite ore reserve accounts for 58.54% of the total boron ore reserves in China, but China has yet no well-developed paigeite ore processing technologies and the commercial utilization is still at the initial stage. Boron resources in salt lakes account for 33.13% of the total boron ore reserves in China, but they are mainly distributed in the Qinghai-Tibet Plateau and are difficult to develop and utilize due to restrictions in transportation and mining conditions. Other boron ores account for 1.69% of the total reserves and only have insignificant implications over commercial production.
China lacks boron resources. The recoverable reserves of....
