 ' Table combines data provided in tables 32 and 33, of the 1977 edition
of this chapter. Wherever possible, detailed information on raw material
source of output (primary—directly from ores and secondary—from
scrap) has been provided. - In cases where raw material source is unreported
and insufficient data are available to estimate the distribution of the total,
that total has been left undifferentiated (primary and secondary). To the
extent possible, this table reflects metal production at the first measurable
state (smelter production) rather than refined production. Thus, production
of lead bullion is credited to the country in which it was produced, and
refined lead produced from imported bullion is not included to avoid double
counting. For some countries, data on actual smelter output are not available
but refined lead output is reported, and these data have been included, appropriately
noted. 
 ' Reported figure. 
 3Lead content of refmed lead, antimonial lead, and impure lead bars produced
from indigenous ores. Previous editions were incorrectly labeled as including
secondary, if any was produced. An additional quantity of secondary lead
is produced (see next line in table). 
 4Lead content of refmed lead and antimonial lead produced from indigenous
ores. 
 ' Series added; not included in 1977 edition. 
 6Series revised to reflect smelter output, rather than refined output, which
appeared in 1977 edition. 
 7Previously reported as primary only. 
 ' Excludes lead content of antimonial lead. 
 ' Lead content of smelter lead and antimonial lead produced from indigenous
ores, and scrap. 
 ' °Revised to zero. 
 "Produced from indigenous ores, in addition to lead content of bullion
produced
from indigenous ores.
