1. Mineral Resources II By: Jhulia Mariz C. Sta. Maria

2. Can we live without minerals? NO

3. Major source of raw materials The food we eat comes from our mineral resources The vehicles that we use comes from our mineral resources the houses we live in comes from our mineral resources www.thehealthyfoodhouse.com www.malabaribusiness.com www.sheknows.com www.huffingtonpost.com news.xinhuanet.com

4. Everything we have and everything we use comes from our mineral resources money.usnews.com www.theguardian.com www.lifehack.org www.malabaribusiness.comwww.celsias.com

5. Mining is the process of extracting minerals and other geological materials from the earth. Born2invest.com

6. 3 Primary Methods of Mining Surface Mining Underground Mining Situ Mining Born2invest.com

7. The process of removing layer Of soil, subsoil, and strata to gain access to the minerals and ore. Surface Mining www..wikipedia.org

8. Underground Mining The process of extracting minerals and ores that are buried too far underground www.evancollis.com.au

9. Situ Mining The process initially involves drilling of holes into the ore deposit. www..wikipedia.org

10. Loss of plants Destruction of habitats for wildlife Leads to extinction of animals, plants and organisms Reducing overall biodiversity Deforestation gslacdao.comv Snowbrains.com

11. Pollution Poisonous chemicals can leak into nearby water supplies en.wikipedia.org www.eoearth.org The soil is removed exposing the soil to the weather, causing particulates to become airborne

12. Health Concern Miners can be poisoned by cyanide through inhalation, ingestion and skin contact. Poisoning from handling the material, or through contact with contaminated air, water or food, is a risk for miners and local residents.

13. How copper is extracted and processed Mining Ore Grinding Concentrating roasting smelting conversion Anode casting Electro –refining ORE is a rock that contains metal GRINDING the ore is crushed and grind to powder CONCENTRATING unwanted materials are remove ROASTING chemical reactions start. Remove some sulphur and dry the ore SMELTING impurities are removed leaving copper and iron sulphide liquid CONVERSION air is blown in liquid copper and iron sulphide forming blister copper ANODE CASTING blister is cast into anodes for electro- refining ELECTRO-REFINING the copper is purified www..wikipedia.org copper is extracted by underground mining

14. How Aluminum is Processed Theodoregray.com raw material bauxite Pass through a bauxite grinder. Alumina is extracted through refining. Refining process Alumina is separated from the bauxite by using a hot solution Pure alumina mixture is heated and filtered, and the remaining alumina is dried Electricity is run between a negative and positive anode. The anode reacts with the oxygen in the alumina The result is liquid aluminium

15. How Gold is Processed The ore is crushed until it is in fine pieces sodium cyanide is mixed with the finely ground rock The gold bearing solution is separated from the remaining solid ore through filtration Zinc is added. It replaces the gold in the gold-cyanide solution. The gold precipitated. www.geoscience.ie

16. How lead is processed The ore is mined www.periodictable.com Ore is treated on a concentrating mill to remove the waste rock from the lead flows to a filter, which removes up to 90% of the water. Refined to remove impurities When the lead has been sufficiently refined, it is cooled and cast into blocks

17. What is the concept of sustainable use of resources? Sustainable use of resources is defined as development that meets the needs of the present without compromising the ability of future generations to meet their own

18. How can we use mineral resources in a sustainable manner? Use only what is required Plant trees, collect rain waters and harvesting Limiting waste material and energy Recycling blogs.holyfamily.catholic.edu.au www.iconfinder.com www.tinley park.org
