Mining
Resources are raw materials that have a mineral origin, althought they can also
Be for vegetable origin. They belong to the primary sector. Mineral resources
Can be clasified as: -Industrial rocks:They are made up of 3 large groups:
Energy rocks (coal, oil... Used to produce energy), Useful rocks (limestone,
Marble... Used mainly in construction) and precious stones (diamond, emerald...
Used in jewellery). -Minerals: They are classified as: useful minerals (iron,
Copper...) Precious metals (gold, silver...) and strategic minerals (uranium,
Coltan...). Coal is found in the basins next to the mountain ranges that were
Formed some 300 million years ago, such as the Appalachians. Oil is found
Mainly in the countries near the Persian gulf. The Gulf osf Mexico... And it is
Often found in close proximity to natural gas. Spain has historically been a
country with one of the richest traditions of mining (gold, silver, uranium,
Mercury...) but today the mining industry has almost completely disappear. The
Country with the most mineral resources is China, next is the United States and
Next Australia. PRODUCING COUNTRIES AND CONSUMING COUNTRIES: Currently, every
Country is trying to use its own energy sources in order not to depend on the countries, however there is still great
Global dependency to the producing countries of oil and natural gas. In order
To control production and prices, the main all produces are grouped together in OPEC (Organization of Petrulium Exporting
Countries). Industry and construction belong to the secondary sector. Industry
Transforms raw materials into manufactured products. Industry has evolved
Quickly, this has involved 3 main stages: First industrial revolution: This
Emerged at the end of the 18th century and was based on energy derived from
Coal. The metal and textile industries were the most important industries at
The time. Second industrial revolution: This was based on energy derieved from
Oil and electricity. It ocurried between 1870 and 1970 and was marked by the
Invention of the combustion engine and assembly line production. The industries
Most affected were the automobile,
Chemicals, iron and steel and household appliance industries. Information and
Automation revulition: in adition to oil, nuclear energy and new renewable
Energy were used. Electronics, information tecnology and biotechnoly were used.
Construction: construction provides housing, transport links and other
Essential cpnstruction servicesfor a countryés habitant. It is an important
Economic engine. Characteristics: smaller construction companies provide
Essential services on a lesser scale, building individual houses and hueses
States, office building and service buildings. Currently, construction has
Grown beyond the needs of the population. This was called ´real state
Bubble´meaning the existenceof a large number of houses at inflated prices that
Cannot be sold. Construction and the landscape:construction is becoming more
Innovative and using materials like glass, but particulary innovative is the
Substantial urban development, which consists of 2 building models: Skyscrapers
And individual family houses.
