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.

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

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

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

ECONOMIST’S VIEW
![Page 9: Members: Jesille Vir Hoylar Mark Jason Sierras Maria Teresa Louise Tumampil Group 5 Presentation](https://reader035.vdocument.in/reader035/viewer/2022062518/56649ea15503460f94ba5122/html5/thumbnails/9.jpg)
Which is more abundant among the three given minerals? Manganese,
Phosphate or coal?

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.

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

INDUSTRIALIST’S VIEW
![Page 13: Members: Jesille Vir Hoylar Mark Jason Sierras Maria Teresa Louise Tumampil Group 5 Presentation](https://reader035.vdocument.in/reader035/viewer/2022062518/56649ea15503460f94ba5122/html5/thumbnails/13.jpg)
From the point of view of the industrialist, mining manganese is a good business because of its abundance, high market value and big demand.
