Group 5 Presentation

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. 

Some Mining Minerals

Manganese

Phosphates

Coal

Jesille Vir Hoylar

GEOLOGIST’S VIEW

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.

Mark Jason Sierras

ECONOMIST’S VIEW

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

Maria Teresa Louise L. Tumampil

INDUSTRIALIST’S VIEW

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