1 Represents recoverable zinc content of domestic ores, concentrates, and tailings.
2 Zinc recovered in all forms from old scrap.

: Imports: Zinc content of ores, concentrates, gross weight of zinc blocks, pigs, and slabs,
old zinc scrap, zinc dross, and skimmings. Export statistics represent zinc in ores,
concentrates, dross, and skimmings, and zinc blocks, pigs, and slabs.

4 Data represents all slab consumed (estimating that U. S. Bureau of Mines account
for 96 percent of all slab zinc consumed) plus the zinc content of pigments and salts made
directly from ores, including the estimated quantity of zinc recovered from old scrap and

consumed in forms other than slab. These data do not include withdrawals for the
strategic Government stockpile.

• Average market price of Prime Western Zinc, f. o. b., East St. Louis, as reported by
E. & M . J.

2 Industry stocks: (a) Smelter gained from Jan. 1, 1952, to Dec. 31, 1957, 144,474: (6) consumers gained from Jan. 1, 1952, to Dec. 31, 1957, 23,068. Supply in the United States for the 6-year period exceeded industrial

s, or 15.8 percent. The excesses by year were: 1952, 29 percent; 1953, 13.8 percent; 1954, 16 percent; 1955, 7.5 percent; 1956, 17.4 percent; and 1957, 14.2 percent.

by the American Zinc Institute represents mainly the derivation by primary producers
from secondary material and inclusion by American Zinc Institute of production from
foreign ore.
