Study Notes
Mineral Resources Overview
- The Philippines is rich in mineral resources due to its location in the Pacific Ring of Fire.
- Mineral resources are non-renewable and serve as essential raw materials for various industries.
Types of Mineral Resources
-
Nonmetallic Mineral Resources:
- More abundant and less expensive than metallic ores.
-
Metallic Mineral Resources:
- Formed by magmatic, hydrothermal, sedimentary, and weathering processes.
Formation Processes of Mineral Deposits
-
Magmatic Processes:
- Involve solidification of magma to create igneous rocks and mineral deposits.
-
Hydrothermal Processes:
- Hot water dissolves metals from rocks or magma, leading to ore deposit formation when metal-bearing solutions precipitate.
-
Sedimentary Processes:
- Result from chemical precipitation in aqueous environments.
-
Weathering Processes:
- Occur in high rainfall areas, altering the landscape and contributing to mineral formation.
Key Mineral Resources
-
Coal:
- A hard, black rock-like substance composed of carbon, hydrogen, oxygen, nitrogen, and sulfur.
-
Crude Oil:
- Flammable liquid made up of hydrocarbons, obtained by drilling through non-porous rock.
-
Natural Gas:
- Found alongside coal and oil, can be liquified through complex processes.
Mining Techniques
-
Mining Definition:
- The extraction of minerals from a natural rock or sediment containing valuable minerals.
Surface Mining
-
General Process:
- Involves removing soil and rocks covering ore deposits, frequently using blasting.
-
Open-Pit Mining:
- Common method creating large holes in the ground for resources like gravel and sand.
-
Strip Mining:
- Removes thin strips of overburden above deposits, depositing waste behind.
-
Dredging:
- Extracts materials from underwater bodies like rivers and lakes.
Underground Mining
- Extracts minerals beneath the earth's surface via tunnels.
- More dangerous and expensive compared to surface mining due to the use of explosives.
Mineral Processing
- A systematic process to extract, refine, and prepare minerals for human use.
-
Sampling:
- Involves taking a portion of material for analysis.
-
Analysis:
- Evaluates valuable components in ores for effective resource management.
Environmental Impact
- Awareness of the need to prevent or lessen environmental impacts resulting from mineral resource exploitation is critical.
