The United States continued as the world's largest producer and consumer of strontium compounds, even though there has been no domestic mining of strontium ores since 1959. Imports dropped sharply for strontium minerals (celestite) from 45 kt (49,699 st) in 1981 to 30 kt (33,075 st) in 1982--the lowest annual tonnage since 1975. More than 99% of the celestite came from Mexico. Strontium compound imports also declined from the 1981 level by about 32% to 1.8 Kt (1,942 st).
