According to "Mineral Commodity Summaries" 1996 report, the world's boron ore reserves of 17,000 Wan t (B 2 O 3), Wan reserve base of 42,000 t (B 2 O 3). The world's largest boron resources are characterized by concentrated distribution, Turkey (30 million tons of reserves, 150 million tons of reserves), the United States (40 million tons of reserves, 80 million tons of reserves), Russia (40 million tons of reserves, 40 million reserves) t), Chile (reserve 8 million tons, reserve base 41 million tons), Peru (reserve 4 million tons, reserve base 22 million tons), Bolivia (reserve 4 million tons, reserves based on 19 million tons) and China and other countries The entire reserve of the world. By the end of 1996, China had identified 63 boron mines with reserves (B 2 O3) of 46.706 million tons, of which A+B+C accounted for 53.8%, which was 25,128,000 tons (the following table). For example, China's boron ore reserves are ranked 5th in the world in terms of A+B+C reserves compared with reserves in other countries. It is also predicted that the total resources of China's boron mines will be about 100 million tons. Among them, Tibet has the largest amount of boron resources, accounting for 48.47% of the country's total resources, Liaoning ranks second, accounting for 28.98%, and Qinghai accounts for 20.7%, ranking third. The sum of the resources of the salt lake boron mines in Qinghai and Tibet accounts for 79.17% of the total resources of the country. Therefore, it can be considered that the salt lake boron resources in China have more potential than the sedimentary metamorphic re-boring boron mines.
