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.
