1. DESCRIBE HOW ORE MINERALS
ARE FOUND, MINED AND
PROCESS IN HUMAN USE

2. What is Ore?
Ore is the rock which the metal is
extracted in a convenient and economical way.
Ore has a composition that is definite. Metals
that occur naturally in the earth’s crust are
called minerals. Minerals that can profitably be
used to get the metal are called ores.

3. Example of Ore Minerals

4. •Uranium

5. •Chalcopyrite

6. •Chalcolite

7. •Bornite

8. •Diamond

9. •Tin Mineral

10. •Gold

11. How Minerals are Found?

12. •Remote sensors that use satellite images and
geochemical surveys are just two ways that
minerals can be located. Many minerals are then
removed through mining or quarrying. However,
liquid minerals, such oil or gas, may be extracted
by pumping.

13. •Minerals can be found throughout the world in
the earth’s crust but usually in such in small
amounts that they not worth extracting. Only
with the help of certain geological processes are
minerals concentrated into economically viable
deposits. Minerals deposits can only be extracted
where they are found.

15. 1. Project Design
•This is the initial stage in formulating a project.
•This involves review of all available data ( geologic
reports, mining history, maps, etc.), government
requirements in acquiring the project, review of
social, environmental, political, and economic
acceptability of the project, and budget and
organization proposal.

16. 2. Field Exploration
•This stage involves physical activities in the
selected project area. This can be subdivided into
three (3) phases: regional reconnaissance, detailed
exploration, and prospect evaluation.

17. 3. Pre-production Feasibility Study
•The feasibility study determines and validates the
accuracy of all data and information collected from
the different stages.
•The purpose is for independent assessors to
satisfy interested investors to raise funds and
bring the project into production.

18. How Ore Minerals are Mine?

19. What is Mined or Mining?
•Mining is a process of extraction from rock seam
or ore.

20. 2 Main Methods of Mining
1. Surface ore mining methods.
A. Open pit ore mining
B. Strip ore mining
C. Placer ore mining
2. Underground ore mining methods.
A. Slope ore mining
B. Shalf ore mining
C. Drift ore mining

21. Surface Ore Mining
A. Open pit ore mining
this is means a big hole
in the ground. The pit in
mine is created by
blasting with explosives
and drilling.

22. B. Strip of mining a mine
that is worked from the
earths surface by the
stripping of overburden.
Especially a coal mine
situated along the outcrop
of a flat dipping bed.

23. C. Placer ore mining the
practice of separating
heavily eroded minerals
like gold from sand or
gravel.

24. Underground Ore Mining
Underground ore mining is used to extract ore
from below the surface of the earth safely,
economically and with as little waste as possible.

25. Underground Ore Mining
A. Slope ore mining is
method of accessing
valuable geological
materials such as
coal and ore.

26. B. Shalf ore mining it is the
principle means access to
an underground ore body
is a vertical opening.

27. C. Drift ore mining is either
the mining of an ore deposit
by underground methods or
the working of coal seams
accessed by adits driven
into the surface outcome
of the bed.

29. How Ore Minerals Process in
Human Life?

30. 1. Smelting is a process of applying heat to an ore,
to extract a base metal. It is a form of
extractive metallurgy. It is used to extract
many metals from their ores, including silver,
iron, copper, and other base metals.

31. 2. Electrolytic process is the use of electrolysis
industrially to refine metals or compounds at a
high purify and low cost. Some examples are the
Hall-Heroult process used for aluminium, or the
production of hydrogen from water.

32. Milling or Mineral Processing
•It is the process of extracting minerals from the
ore, refining them, and preparing these minerals
for use.
•It is an art of treating crude ores and minerals
products in order to separate the valuable
minirals from the waste rock.

33. Primary Steps in Mineral Processing
1. Sampling is the removal of portion which a
whole needed for the analysis of this materials.

34. 2. Analysis is important to evaluate the valuable
component in an ore. This includes chemical,
minerals and particle size analysis.

35. 3. Comminution – is the crushing and grinding
of a ore to reduce it to smaller or finer
particles.

36. 4. Concentration – involves the separation of
valuable minerals from the raw materials.

37. 5. Dewatering – this involves filtration and
sedimentation of the suspension and drying of
the solid materials harvested from this
suspension.
