1. Earths Natural Resources/Minerals/Mining

2. Earth’s Natural Resources

3. Natural Resources
Materials or components that are derived from the natural environment
Can be renewable or non-renewable
Studying natural resources has become a focus of environmental science because of their rapid depletion/exploitation

4. Renewable Resources (Raw Materials)
Water, Animals, Timber, Fruits/Veggies

5. Renewable Resources (Energy)
Can be regenerated within a lifetime

6. All Renewable’s Are NOT Equal

7. Non-Renewable Resources
Cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate, once depleted there is no more available for future needs
Ex: fossil fuels, mineral ores

10. What Does the Future Hold??

11. Manufacturing Creating goods from raw materials
Requires a great deal of raw resources and fossil fuels
Highly processed materials also creates waste products

12. Why Use Resources Useful for social purposes
Ex: Development of technology for education or medical uses
Useful for economic reasons
Ex: Tax revenue, job creation

13. Minerals Any of various natural substances, such as:
An element, such as gold or silver
An organic derivative, such as coal or petroleum
A substance, such as stone, sand, salt, or coal that is extracted or obtained from the ground or water

14. Minerals
Every segment of society uses minerals and mineral resources everyday. The roads we drive on and the buildings we live, learn, and work in all contain minerals!!

15. Mineral Resource Use Ores contain minerals
Processed to remove the metal
Transported to manufacturing facility

16. Mining Often needed to access the mineral ores 4 major types Surface
Open pit
Strip
Underground

17. Surface Mining
Overlaying rock/topsoil is removed to access the mineral ore

18. Open Pit Mining Used when surface is unstable
Mineral ore removed from large quarry

19. Strip Mining Similar to surface mining
Layers are removed like an onion

20. Underground Mining Also called hard rock mining
Used to excavate hard rocks containing minerals, usually metals

22. Mining Waste
Mining produces an unbelievable amount of waste by-product
Mining waste include waste generated during the extraction, refining, and processing of minerals
-Extraction is the first phase of hard rock mining which consists of the initial removal of ore from the Earth

23. Mining Waste
- Refining follows and is the initial attempt at liberating and concentrating the valuable mineral from the extracted ore, operations include: grinding, washing, crystallization, filtration, sorting, sizing, drying, etc.
