Lead is a dense, toxic,
bluish-gray metallic element, and is the heaviest stable
element. Lead was one of the first known
metals. The ancients used lead in face
powders, rouges, mascaras, paints, condiments, wine preservatives,
and water supply plumbing. The Romans were slowly poisoned
from lead because of its diverse daily usage.
Lead is usually found in
ore with zinc, silver, and most often copper. The most common
lead ore is galena, containing 86.6% lead. Cerussite and
angleside are other common varieties of lead. More than
half of the lead currently used comes from recycling.
Lead is used in building construction, bullets
and shot, tank and pipe lining, storage batteries, and electric
cable sheathing. Lead is used extensively
as a protective shielding for radioactive material, i.e.,
X-ray apparatus, because of its high density and nuclear
properties. Lead is also part of solder, pewter, and fusible
alloys.
Lead futures and options trade at the London
Metal Exchange (LME). The lead futures
contract calls for the delivery of 25 metric tons of at
least 99.970% purity lead ingots (pigs). The contract is
priced in terms of US dollars per metric ton. Lead first
started trading on the LME in 1903.
Prices – Lead prices took off in the
latter half of 2003 along with the rest of the basic metals
complex. Lead prices between 2000 and the middle of 2003
bounced back and forth within a range of approximately to
per metric ton. However, in mid-2003, lead prices entered
a major bull market and rallied from the area all the way
up to approximately by the end of the year, a rally of about
70%.
Supply – World smelter production of
lead (both primary and secondary) in 2002 fell –1.2%
to 6.390 million metric tons from 6.470 million metric tons
in 2001, but was only modestly lower than the record production
level of 6.580 million metric tons in 2000. The world’s
largest smelter producers of lead (both primary and secondary)
in 2002 were the US with 21.6% of world production, followed
by China with 20%, Germany with 6.1%, and the UK with 5.8%.
US mine production of recoverable lead fell
to a 6-year low of 440,000 metric tons in 2002 from 454,000
in 2001. Missouri was responsible for 97% of US production,
with the remainder produced mainly by Idaho and Montana.
Lead recovered from scrap in the US (secondary production)
fell to a 6-year low of 1.106 million metric tons in 2002
from 1.113 million metric tons in 2001. That is more than
twice the amount of lead produced in the US from mines (primary
production). The value of US refined lead production in
2002 was million, down from million in 2001 and well below
the record high of million posted back in 1979.
Demand – US lead consumption in 2002
rose slightly to 1.673 million metric tons from 1.652 million
metric tons in 2001, and that was only slightly below the
record consumption level of 1.680 million metric tons posted
in 1999.
Trade – The US relied on imports
for 18% of its lead consumption in 2002. US imports of lead
pigs and bars in 2002 fell to a 9-year low of 210,000 metric
tons. US lead exports in 2002 were comprised by ore concentrate
(241,000 metric tons), scrap (106,000 metric tons), unwrought
lead (31,400 metric tons), and wrought lead (11,700 metric
tons).
