2. Which are of great
industrial use to man are
copper, lead, zinc, mercur
y, magnesium, and
titanium.

4.  Copper has been used by
man for thousand of years.
It is used in the
manufacture of bronze and
brass. Copper occurs as a
free mental in nature but it

10. Is more abundant than iron.
However, as a constituent of
the earth ‘s crust the
occurrence of large deposits
of aluminum is rare

11. SAMPLE PICTURE

12. Is very similar to aluminum
both in properties and uses.
Like aluminum it occurs in
nature with several mineral
but it requires elaborate
metallurgical processes to
transform it into a mental.

13. SAMPLE PICTURE

14. Isalso light weight strength and
resistant to and corrosion When
compared with aluminum and
magnesium ,titanium is heavier
but it retains its strength even
when subjected to higher
temperatures.

15. SAMPLE PICTURE

16. Gold and silver are the two
precious metals which are both
found in the Philippines. Gold
may be in the form of flakes or
nuggets and when found in
loose materials , placer mining
method are used.
