Here’s a concise overview of mining, minerals, and related concepts:
1. Mining
– Definition: The process of extracting valuable minerals or other geological materials from the Earth.
– Types:
– Surface Mining: Open-pit, strip, placer (for gold, coal, etc.).
– Underground Mining: Shafts/tunnels (for diamonds, metals).
– Deep-sea Mining: Extracting minerals from ocean floors (e.g., polymetallic nodules).
– Key Concerns: Environmental impact (deforestation, pollution), worker safety, sustainability.
2. Minerals
– Naturally occurring inorganic solids with a defined chemical composition and crystal structure.
– Categories:
– Metallic Minerals: Gold, iron, copper (used in electronics, construction).
– Non-Metallic Minerals: Quartz, gypsum (used in glass, cement).
– Energy Minerals: Coal, uranium (fuel sources).
3. Key Minerals Mined Globally
| Mineral | Uses | Major Producers |
|—————|——————————-|————————-|
| Iron Ore | Steel production | Australia, Brazil |
| Copper | Wiring, electronics | Chile, Peru |
| Lithium | Batteries (EVs) | Australia, Chile |
| Rare Earths | Magnets, renewables | China |
| Gold | Jewelry, finance | China, Russia |
4. Challenges & Future Trends
– Sustainability: Recycling e-waste for minerals (e.g., cobalt).
– Green Mining: Reducing water/energy use; carbon-neutral practices.
– Battery Minerals Demand: Lithium & cobalt for EVs driving new mines..jpg)
