Lead was probably one of the first metals to be produced by man, being known
since 3500 B.C., in agreement with archaeological discoveries done in Egypt. The
oldest lead piece is in the British Museum and dates from 3800 A.D.. The manner
in which prehistoric people extracted lead from its minerals is not well-known.
However, there are vestiges of very rudimentary furnaces, done of stone, where
these people heated up the lead minerals with bonfires (that burned wood and
coal) to extract the element

Features & Applications:
Although uses for lead have decreased over the years, it still plays an
important part of everyday life particularly as the starter mechanism for
automobiles. The lead-acid battery, which performs this function, dominates the
usage of lead, consuming over 80% of world production. The remaining 20% of
production is divided into numerous end-uses including: underwater cable
sheathing, ammunition, glassware, solder and roof sheeting.
Lead alloys are used in a range of applications including:
Solder:
lead solder is used extensively by the electronics industry
Terne plate: iron
and steel can be protected against corrosion by coating the surface with a lead
based alloy.
Brass and Bronze Products:
lead had traditionally been used in bearings and bushings
to reduce wear and friction in certain type of machinery.

Over recent years the demand for lead has increased. This
is mainly a result of an increase in Asia's automobile population and the
growing popularity of the e-bike, particularly in China. In fact, the e-bike now
consumes over 8% of world lead production. With the industrial growth of other
Asian countries, the battery has a continuing and expanding role to play.
