WHAT ARE MINERALS?
Nature provides us with many resources, some
on the Earth's surface and others buried deep
underground. Underground resources, known as
minerals, need to be extracted and refined for
various uses.
Minerals are naturally occurring substances
found in the Earth's crust that have specific
chemical compositions and physical properties.

TYPES OF MINERALS
TYPES OF MINERALS
Metallic Minerals:
These include iron, aluminium,
gold, and copper. They are used to
make tools, utensils, electrical
wires, and even jewellery.
Non-Metallic Minerals
These include limestone, precious
stones, salt, coal, and petroleum.
Coal and petroleum are important
as they are used as fuel (like for
cooking or running vehicles).

M I N I N G :
Mining involves extracting
minerals from the Earth's crust
through methods like surface
mining (open-pit mining,
quarrying) and underground
mining (shaft mining, drift
mining).
R E F I N I N G :
Refining is the purification
process for metallic minerals
like iron, copper, and gold
through smelting, while non-
metallic minerals like salt, coal,
and petroleum undergo
purification, distillation, and
chemical treatments to remove
impurities.
