Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company accounted for 90 percent of the total shipments of manganese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.

Without manganese the steelmaking industry would be very seriously handicapped. The metallurgy of manganese has been developed around the high-grade ores, and unfortunately, our reserves of high-grade ores are very limited.
