  1/Recoverable mine production is estimated for 1859-99.
  2/Imports Ore: 1904-09 were estimated (Minerals Yearbook 1926) and for 1910-36 were zinc content of general imports.
  3/Exports Ore: 1897-1915 zinc content estimated at 50% of ore shipped; 1907-15 virtually all willemite concentrate
(50% zinc).
  4/Data through 1981 are reported consumption of slab zinc; 1982 forward, data are apparent consumption of slab zinc.
  5/1880-1900 data for zinc oxide from ore; 1901-07 data for zinc oxide and zinc lead from ore; 1908-18 data for pigments
from ore; 1919-24 data for pigments and salts from ore; 1925-56 data for zinc oxide from ore; 1957-88 includes ore directly
for galvanizing.
  6/Based on apparent consumption of slab zinc plus zinc content of ores and concentrates and secondary materials used to
make zinc dust and chemicals.
  7/Net import reliance is expressed as a percent of apparent consumption.  Net import reliance is defined as exports minus
imports plus adjustments for changes in industry and Government stocks.  Apparent consumption in U.S. equals mine production
plus old scrap plus net import reliance.
