LEAD: THE VERSATILE METAL

Over the centuries lead's unique properties have been harnessed in countless ways in the service of man and today it is still one of the most widely used and versatile materials in existence.

Its softness and low melting point make lead very easy to handle and fashion. Its high resistance to corrosion makes it ideal for weatherproofing buildings and for equipment used in the manufacture of acids. Lead's high density makes it particularly appropriate as a shield against radiation in the nuclear industry and in hospitals. For the same reason lead is also good at stopping sound waves and so is used to reduce noise from machinery in factories and from engine rooms on ships.

However, the most important use of lead today is in the lead-acid battery which provides power in numerous situations. The most familiar use of the lead-acid battery is to start our cars and other vehicles, but they are also used to power electric vehicles and to provide emergency power when the electricity fails.

The qualities of lead are unrivalled and it is irreplaceable in many of its uses. Consequently this versatile metal will be needed as much in the future as it has been in the past.

SOURCES AND PRODUCTION

Lead metal is described as being either primary or secondary. Primary lead is produced directly from mined lead ore. Secondary lead is produced from scrap lead products which have been recycled.

Around 3 million tonnes of lead are mined in the world each year.  Lead is found all over the world but the largest mining countries are Australia, China and the United States, which between them account for more than 50% of primary production.

The most common lead ore is galena or lead sulphide. Other elements frequently present include zinc and silver. In fact lead ores constitute the main sources of silver, contributing substantially towards the world's total output.

Lead is obtained from galena by a process called smelting. This involves roasting the ore to remove the sulphur and to obtain lead oxide which is then reacted with coke in a furnace. The resulting lead bullion contains many impurities such as silver and gold (hence the name bullion) as well as antimony, arsenic, copper, tin and zinc. These impurities are then removed by various refining steps to obtain pure lead.

RECYCLING

A further 3 million tonnes of lead are produced from secondary sources each year, by recycling scrap lead products such as sheet, pipe and batteries. In fact in the western world today more lead is produced by recycling than by mining.

At least three-quarters of all lead used goes into products which are suitable for recycling. This is why lead has the highest recycling rate of all the common non-ferrous metals.

The use of secondary metal makes some important contributions to the environment:

Firstly, the recovery of lead from scrap requires far less energy than smelting from ore.

Secondly, recycling keeps unwanted products out of the waste stream and puts them to good use.

Thirdly, recycling conserves our natural resources for the benefit of future generations.
