 Finished products: can be used or consumed inmediately.
 Semi-finished or intermediate products: used with other components to
make a product.
Industry transforms raw materials into:
 Craftsmanship: production process was manual; craftspeople (artisans)
used his own tools; products were expensive; each product was unique.
 Industrial Revolution (XVIII century, England, textile and metallurgical
industry).
Energy: hydropower and coal (steam water machine).
Workshop were replaced by machines, powered by engines. Machines
required less labour and produced more goods in less time (productivity).
Prices decreased. Workshop went to bankruptcy. FACTORIES.

10. Minerals come from:
 Opencast Mines:minerals or rocks are found near the surface easy
to extract, more profitable.
 Underground: complicated and dangerous; need to dig shaft and
tunnels, water needs to be drained and air supply has to be constantly
renewed.
Process to extract minerals from underground.

13. 4.1 TYPES OF INDUSTRIES.
INTERMEDIATE GOODS INDUSTRY.
There are different ways of classifying industries. For example, one criterion is to
identify the end user of the product so we can distinguish between industries
that manufacturate components to use in other industries and thouse industries
that produce goods ready for consumption.
 Make goods that can’t be inmediately consumed. Transform raw materials
into intermediate goods. These goods are raw materials for other industries.
 This industry is referred to as heavy industry because of the large
quantities of resources needed (raw materials, workers, capital and space).
For example, iron and steel industries, heavy chemical, cement, etc. 13

14. 14
EQUIPMENT INDUSTRY.
Use goods manufactured in other industries as raw materials. For
example, construction industry or mechanical.
CONSUMER GOODS INDUSTRY

15. CONSUMER GOODS INDUSTRY
 Produce goods ready for consumption.
 These industries are called LIGHT INDUSTRIES (wood and furniture, food
and drinks, textile, footwear, light chemical).
 These industries require less workers and capital, the size of the
production is relatively small.
ACCORDING TO LEVEL OF
TECHNOLOGY.:
HI-TECH INDUSTRY.
 Advanced technology (microelectronics, telecommunications, information
technology, aerospace industry).
 Industries need highly-skilled workers and capital investment.
 Scientific research is needed so these industries locate close to
universities.
15

16. 4.2. COMPANIES.
Industrial activities are run by businesses and companies.
 Ownership: whoever who buy shares
in the stock market.
 Money (invested and cash).
 Executive Board.
 Influence over economics and politics.
BY SIZE.
 Small-size (up to 50 workers)
 Medium-size (up to 250 workers)
 Large companies (more than 250 workers)
BY ITS ORGANIZATION.
 Limited Company: owned by one or more owners, but a limited
number.
 Public Company: owned by the people who have shares in the
company.
BY WHERE THEIR CAPITAL COMES FROM.
 Public: capital from the State and are managed by the State.
Private: a businesses own the capital and manage the company.
 Thousand of workers.
Marketing Investment.
 Markets Research (to sell
more).
 Distribution of factories,
suppliers and markets worldwide.
A GREAT COMPANY FEATURES.

17. 6.4.CONCENTRACIÓN DE LA EMPRESA
Complejidad de la industria = división y especialización de la producción
 HORIZONTAL CONCENTRATION: companies at the same stage of
production process group together. For example, cars industry or metal
industry.
 VERTICAL CONCENTRATION: companies expands its business into
areas that are in different points on the same production process: for
example, a company owns its supplier and its distributor.
Especialización = concentración de empresas para ser competitivas

7.2. DIVISION OF THE LABOUR.
TECHNICAL DIVISION.
 Production process is organised: workers are in charge of only a
part of the production process.
 Coordination of all workers involved and machinery they work with.
 SOCIAL DIVISION OF THE LABOUR.
 Hierarchies are established between groups of workers . Some
are in charge of making decisions and instructing other workers.

19. 8.INDUSTRY WORLD FACTORS OF LOCATION.
 Businesses: reduce costs and sell and make more money.
 Remain competitive, improve quality of the goods, keep production
costs low.
 Factors of location influence in how to reduce costs and increase profits.
 INDUSTRIAL REVOLUTION (XIX and XX century): heavy industries
located close raw materials deposits (coal and iron) and sources of
energy (coal) to reduce costs of transportation.
CURRENT LOCATION TRENDS.
 Some industries choose to stay where they have traditionally developed
their activities because ….
 Good infrastructure, associated or complementary industries, technical
and assistance services, …
 Japan, Western Europe, North-East USA.
 Industries that need unskilled workers such as textile.
 Labour force is cheap (China, India, south-east Asia)
 Some industries choose locations near to universities:
 Highly-skilled workers, advanced technology and research facilities
(science parks.
 Example: Silicon Valley (California).

27. OIL REFINERY
An oil refinery converts crude oil into:
- Motor fuel (gasoline, diesel).
- Jet aircraft fuel (kerosene).
- Heating fuel oil.
- Lubricating oil.
- Asphalt.
LOCATION:
- Far from residential areas.
- Refineries which use a large
amount of steam and cooling water
need to have an abundant source of
water often located to
navigable rivers and on a sea shore.
- Navigable rivers or sea shore gives
access to an easy transportation.

39. NUCLEAR POWER PLANTS IN SPAIN.
In 1964, Spain began construction on its first of three nuclear reactors and completed construction in 1968.
This became the first commercial nuclear reactor. In the 1970s, Spain began construction on seven second
generation reactors, but only completed five. A moratorium was enacted by the socialist government in
1983. Spain stopped the building of new nuclear power plants in 1984.
Nuclear energy produce 20% of Spain electricity.
39

40. • On 26 April 1986 an
explosion and fire released
large quantities of radioactive
particles into the atmosphere,
which spread over much of
the Soviet Union and Europe.
RISKS OF THE NUCLEAR ENERGY:
CHERNOBIL AND FUKUSHIMA.
40
Chernobyl disaster was worst nuclear power
plant accident in history. The battle to contain
the contamination involved over 500,000
workers. During the accident itself, 31 people
died, and long-term effects such as cancers are
still being investigated.

41. 41

42. There was still fear that the reactor could explode again, a new containment
structure was planned and to prevent further release of radioactive material.
This involved a quarter of a million construction workers who all reached
their official lifetime limits of radiation. By december 1986, a large
concrete sarcophagus had been erected to seal off the reactor and its
contents.
42
An area originally extending 30 kilometres in all directions from the plant is
officially called the "zone of alienation". It is largely uninhabited, except for
about 300 residents who have refused to leave.

43. FUKUSHIMA, JAPAN. 2011.
43
On March 11, 2011 and tsunami hit the
nuclear power station. As a result,
three nuclear reactors meltdown.
Some 300.000 people were evacuated
from the area. World Health
Organisation estimates that 70% of
children evacuated are in risk of
suffering thyroid cancer and 7%
leukemia.
