TABLE III.-Maximum iron ore supplies for the United States, 1950–70
(Millions of gross tons)
1 Net United States supply (imports minus exports).
TABLE IV.-Iron ore reserves of the United States, Jan. 1, 1950
[In gross tons)
1 Material of such nature and geographic and geologic distribution as to be considered usable under present economic and technologic conditions. (See submarginal column.)
• Material that may become usable under future conditions. This includes: Material of lower grade than is now being mined. Material of usable grade but in deposits less than minable size. Deposits of minable size but containing impurities in harmful quantities. Deposits technologically satisfactory but too remote from transportation and blast furnaces for present use.
• Approximate. • The commercial reserves of the Northeastern States are in New Jersey, New York, and Pennsylvania; the submarginal material includes the low-grade ores of Maine and Ohio. Concentrates. From Hewitt, Geo. W., Iron ore supply for future:
American Iron and Steel Institute Meeting, May 21-22, 1947, p. 7.
& Nine-tenths of the commercial ores of the Southeastern States are in Alabama; the other tenth is in Georgia, Kentucky, North Carolina, Tennessee, Virginia, and West Virginia. Submarginal ores are divided between Alabama and the other Southern States.
The enormous taconite resources are included in the "Submarginal" column. 'In the States west of the Mississippi River, Utah and Texas have five-eighths of the commercial reserves Source: Prepared by United States Geological Survey.
