In heavy industry, raw materials are transformed into semi-finished products that are then used in other industries. Heavy industries require large capital investments. They occupy large areas near energy sources and raw materials. Heavy industries include:
HEAVY CHEMICAL INDUSTRY
It uses many different raw materials (coal, hydrocarbons, sulphur, salts, etc.) to produce raw materials for other industries (fuels, fertilisers, acids, explosives, etc.).
It transforms non-ferrous minerals into metals (e.G. Aluminium and copper) and semi-finished products (e.G. Laminates, shaped and molten metals) for other industries.
It transforms iron into steel to make machinery or rails, amongst other elements required by many other industries.
All industries that produce energy using different sources, e.G. Thermal power stations.
This industry uses products from heavy industry as raw materials to make the materials and machinery required by other industries. It also requires large industrial complexes, large investment and a skilled workforce. These industries include:
THE METALLURGICAL PROCESSING INDUSTRY
It makes industrial machinery for light and heavy industry, and agricultural transportation, electrical and computer parts, etc.
CARGO TRANSPORTATION INDUSTRY
It includes the aeronautics industry (aeroplanes, helicopters, etc.), the naval industry (ships) and the railway industry (carriages, rails and train components).
It makes materials for buildings and public works.
