Extraction
of
Metals



Blast
Furnace-
The
reduction
of
Iron

The
extraction
of
iron
from
its
oxide
is
done
using
carbon,
in
industry
this
is

done
by
using
coke
in
tall
towers
called
blast
furnaces.
This
is
a
continuous

process
and
the
furnaces
can
run
for
many
years
at…

Extracting
zinc
from
zinc
sulphate

Zinc's
ore
is
not
an
oxide
when
extracted
from
the
earth
it
is
a
sulphide.

However
sulphides
can
not
be
reduced
like
oxides
in
a
blast
furnace.
So
the
ore

is
converted
to
an
oxide
by
heating
it
in…

Extracting
copper-
New
method

The
modern
day
method
of
extracting
copper
does
not
require
thermal

decomposition
to
convert
the
copper
carbonate
into
an
oxide.
Instead
to

convert
the
carbonate
a
solution
is
made
that
contains
Cu2+
ions.
This
is
done

by
spraying
copper
mining
waste
with
an
acid…

Extraction
of
Titanium-
Displacement
reduction


Titanium
is
a
very
strong
and
durable
metal
and
has
quite
a
high
demand
for

building
materials
and
armour
plating
military
purposes.
Titanium
can
not
be

reduced
by
carbon
as
producing
titanium
carbide
weakens
the
titanium

causing
it
to…
