2. Mining  is the work or business of taking minerals from the earth. A hole or tunnel is dug in the ground to take out metals, coal, salt, or other minerals.  is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam.

3. Some Mining Minerals Manganese Phosphates Coal

4. Jesille Vir Hoylar GEOLOGIST’S VIEW

5. MANGANESE MANGANESE= Manganese is used extensively to produce a variety of important alloys and to desulfurize and deoxidize steel.

6. PHOSPHATES Inorganic compounds containing phosphorous. Used in fertilizers (as plant nutrient) and in detergents (as 'builders' or water softeners)

7. COAL Coal, a fossil fuel, is the largest source of energy for the generation of electricity worldwide.

8. Mark Jason Sierras ECONOMIST’S VIEW

9. Which is more abundant among the three given minerals? Manganese, Phosphate or coal?

10. MANGANESE IS MORE ABUNDANT IN THE THREE Manganese is relatively abundant, constituting about 0.085% of the Earth's crust. Among the heavy metals, only iron is more abundant. Most manganese occurs in deposits of the oxides, hydrous oxides or carbonates.

11. The economist’s view varies both in price and demand. PRICES: MANGANESE=$ 3.99 per gram PHOSPHATE =$ 0.00043 per gram COAL =$ 0.00018 per gram DEMAND: MANGANESE = Higher demand from industrialized countries PHOSPHATE = Higher demand from agricultural countries COAL = High demand from both industrialized and agricultural countries

12. Maria Teresa Louise L. Tumampil INDUSTRIALIST’S VIEW

13. From the point of view of the industrialist, mining manganese is a good business because of its abundance, high market value and big demand.
