Transport

Every journey you make depends on minerals, whether by car, train, plane, boat or foot. Aggregates (crushed rock and sand and gravel) are used for roads and footpaths, while railway tracks made from steel are laid on aggregate (known as ballast). Airports, railway stations and shipping ports all use large amounts of construction minerals to build them.

Cars, trains, planes, boats and bicycles are all made using metals such as steel and aluminium. Aircraft engines depend on mixtures of metals called alloys which are made from metals including nickel, cobalt, chromium, aluminium and titanium. In every car there are over 15,000 components made from minerals.
