Iron Extraction and Steel Production Processes
Iron Extraction and Steel Production
Iron Ore Extraction Process
The process begins with the extraction of iron ore from the mine, where all the raw material is collected. Once extracted, the ore is transported to a processing area where it is crushed into a fine, dust-like consistency.
This fine mineral powder (along with its impurities) is then transferred to a series of trays equipped with rotating paddles and water. This step aims to separate the earth and isolate as much iron-rich material as

Relief Configuration of the Iberian Peninsula
The configuration of the Iberian Peninsula’s relief is characterized by three basic features:
- Massive Form: This is due to the peninsula’s large width and generally straight coastline, with few significant indentations. This limits the influence of the sea inland.
- High Average Altitude: At 660 meters, this is due to the presence of high mountains. The interior of the peninsula is composed of an extensive upland core, the Meseta Central (Plateau).
- Peripheral
Renewable Energy Sources: Untapped Potential
Hydraulic Power
Hydropower is generated by the falling mass of water to save a difference in level. Currently, it is used to generate electricity in power plants. Reservoirs and dams are associated to retain the water and create the necessary gap for the fall of the water.
Advantages
- Minimum maintenance cost.
- It does not pollute.
- Favors navigable rivers.
Disadvantages
- Geographical limitations.
- High cost.
- Sometimes it creates social conflicts.
Tidal Energy
It is based on the exploitation of tidal currents.

Electrical Circuits
Electric current is formed by electrons jumping from one atom to another, and this movement generates electricity.
Voltage is the potential difference that makes the electric current flow through a conductor. A potential difference, tension, or voltage must exist for electric charges to move through a conductor in a given time.
Ohm’s Law
- Current = Amps = I
- Voltage = Volts = V
- Resistance = Ohm = R
In a continuous electric circuit, electrical power is produced by the movement of electrons.

Catalonia’s Climate Zones
- Mediterranean Trend (Continental): Located west of the Central Depression. Characterized by wider thermal oscillation and scarce rainfall with prolonged drought periods.
- Oceanic Climate: Found in the Vall d’Aran, influenced by the Atlantic. Features mild temperatures and frequent rainfall throughout the year.
- Mountain Climate: Situated in the highest peaks of the Pyrenees and their foothills. Experiences low temperatures and abundant rainfall. Includes downhill (above 2,300
Understanding Rocks, Weathering, and Limestone Landscapes
Rock Types: Igneous, Sedimentary, and Metamorphic
1. Igneous Rocks: Formed from volcanic activity. They are made of tiny crystals that formed as the volcanic rock cooled down. Examples include granite and basalt.
2. Sedimentary Rocks: These rocks are laid down in layers. They are made of other rocks that have been eroded and transported, or from the remains of plants and animals. Examples include limestone, chalk, and coal.
3. Metamorphic Rocks: These are rocks that have been changed due to intense
