Study Notes
Types of Mineral Resources
- Metallic minerals:
- Ferrous minerals (iron, manganese)
- Non-ferrous minerals (copper, zinc, gold)
- Non-metallic minerals:
- Silicates (quartz, feldspar)
- Oxides (bauxite, rutile)
- Carbonates (limestone, dolomite)
- Phosphates (apatite)
- Energy minerals:
- Fossil fuels (coal, oil, natural gas)
- Nuclear energy (uranium)
Formation of Mineral Deposits
- Magmatic deposits:
- Formed from magma cooling and solidification
- Examples: copper, nickel, platinum
- Hydrothermal deposits:
- Formed from hot water rich in minerals
- Examples: gold, silver, copper
- Sedimentary deposits:
- Formed from sedimentation and concentration of minerals
- Examples: iron, copper, phosphates
- Metamorphic deposits:
- Formed from transformation of existing rocks
- Examples: marble, quartzite
Extraction and Processing of Minerals
- Open-pit mining:
- Used for shallow deposits
- Involves removing rock and soil to expose mineral deposit
- Underground mining:
- Used for deeper deposits
- Involves excavating tunnels and shafts to access mineral deposit
- Mineral processing:
- Involves separating minerals from waste rock
- Methods: crushing, grinding, flotation, smelting
Energy Resources
- Renewable energy resources:
- Solar energy
- Wind energy
- Hydro energy
- Geothermal energy
- Non-renewable energy resources:
- Fossil fuels (coal, oil, natural gas)
- Nuclear energy (uranium)
Conservation and Sustainability
- Importance of conservation:
- Reduces waste and environmental impact
- Extends lifetime of mineral deposits
- Sustainable mining practices:
- Minimizing environmental impact
- Reclaiming and rehabilitating mined land
- Implementing recycling and reuse programs
