Boron: A Review of 1994 Activities

The United States was the world's largest producer and consumer of boron compounds during 1994. According to US Bureau of Mines (USBM) estimates, boron mineral concentrate and chemical production in the United States totaled about 1.05 Mt (1.15 million st), yielding 560 kt (617,000 st) of B203, for a total estimated value of $370 million. This production level was about 2% less than 1993 revised figures. The United States continued to provide nearly all of its own boron supply while maintaining a strong position as a source of sodium borate products and boric acid for export. Domestic employment in the mining and beneficiation of boron products during 1994 was 900 people, about the same as in 1993. USBM estimated total world production of boron of about 2.3 Mt (2.5 million st), yielding 1.1 Mt (1.2 million st) of B203. World production during 1994 was about the same as during 1993. USBM estimates US reserves to be about 210 Mt (231 million st) of ore and world reserves to be about 630 Mt (694 million st) of ore.
