HOW MINERAL ORES ARE
FOUND, MINED AND
PROCESSED

2. Minerals Important to Society

3. HOUSEHOLD

4. toothpaste contains fluoride from
fluorite mineral
Face powder contains talc – the
softest mineral

5. Salt – sodium chloride (NaCl)
from chemical compound
Kitchen utensils – made of aluminum, a light and
durable metal, and stainless wares that contains mostly
of iron, chromium and carbon

6. Copper is mostly used in electrical
wiring because it is less expensive
minerals such as silicon, silver and gold
are used as components of gadgets

8. a form of carbon, is
considered as the most
precious mineral.
- contain aluminum oxide.
Emeralds are from the
mineral beryl. Quartz is
also considered as a semi-
precious mineral
Rubies and sapphires

9. Iron steel - a combination of iron and carbon and concrete that
contains limestone, lime and chalk that make them strong and
stand still against strong wind and earthquake. They also use
glass made mainly of quartz and silica. Floors are made up of
granite and marbles. Aluminum are used in window and door
panels.
construction

10. alloys like stainless steel that primarily
composed of iron, chromium and carbon in
their tools.
Titanium is a strong but very light metal
that is used for teeth transplant

11. Power plants use
minerals to provide us
electricity and energy

13. How are these mineral
ores processed for
human use?

16. It is utilized to extract
ore minerals that are
close to earth’s
surface

17. It is a type of mining
that is carried out when
the rocks, minerals, or
precious stones are
located at a distance far
beneath the ground.

19. Mineral processing is the process of extracting minerals from the ores,
refining them and preparing these minerals for use.
is a removal of a portion which represents a whole
needed for the analysis of this material.

20. Mineral processing is the process of extracting minerals from the ores,

to evaluate the valuable components in
an ore

22. Mineral processing is the process of extracting minerals from the ores,
refining them and preparing these minerals for use.
is the process where the valuable components of the ore are
separated through crushing and grinding. This process begins by
crushing the ores to a particular size and finishes it by grinding the
ores into a powder form.

23. Mineral processing is the process of extracting minerals from the ores,
refining them and preparing these minerals for use.
involves the separation of the valuable
minerals from the raw materials.

24. involves the separation of the valuable
minerals from the raw materials.

25. Mineral processing is the process of extracting minerals from the ores,
refining them and preparing these minerals for use.
uses the concentrates to convert it to usable
minerals. This involves filtration and
sedimentation of the suspension and drying of
the solid material harvested from this
suspension.
