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
GEOLOGIST’S VIEW
Jesille Vir Hoylar
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
Mark Jason Sierras
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
PHOSPHATE
COAL
=$ 3.99 per gram
=$ 0.00043 per gram
=$ 0.00018 per gram
DEMAND:
MANGANESE
PHOSPHATE
COAL
= Higher demand from industrialized
countries
= Higher demand from agricultural
countries
= High demand from both industrialized
and agricultural countries
INDUSTRIALIST’S VIEW
Maria Teresa Louise L. Tumampil
From the point of view of the industrialist,
mining manganese is a good business
because of its abundance, high market
value and big demand.
