2. Magnesium production methods
One of the features of the magnesium industry is the wide
variety of production processes. Relative to an industry,
which has been manufacturing a product commercially for
close to one hundred years, it is somewhat strange that there
are over 10 different processes for producing magnesium.
Unlike many other industries, there is
no one particular dominant technology
used for most of the world’s production.

3. Raw Materials
There are six sources of raw materials for the production of magnesium:
magnesite, dolomite, bischofite, carnallite, serpentine and sea water.

4. Raw materials & formula

5. Magnesite
• In nature, this material is composed mainly from
carbonated magnesium and contains low
concentrations of calcium, iron and manganese as
impurities.
• Magnesite belongs to the calcite group,which is a group
of carbonates that are similar in their physical
characteristics.
• Magnesite is usually produced when rocks rich in
magnesium come into contact with carbonate-rich
solutions thereby producing a first degree
metamorphosis. The Magnesite does not normally
produce crystals with a defined form. It has a crystalline
structure similar to calcite and it is white.
• Magnesite is common in Brazil, Austria, Korea, China
and the West Coast of the United States of America, and
it is extracted by mining. The magnesium concentration
by weight is 28.8%.

6. Dolomite
• This is composed mainly of the double salts of
magnesium and calcium carbonate, and contains low
concentrations of iron and manganese as impurities.
• Dolomite is usually colorless and looks like small
diamond-shaped crystals.
• Dolomite is formed as a result of calcite
transformations in the presence of magnesium ions.
• Dolomite rock is useful in the chemical industry for
the preparation of magnesium and serves as
construction and decoration stone. Common
deposits can be found in England, Germany,
Brazil,Norway and Mexico.
• The magnesium concentration in dolomite by weight
is 28.8%.

7. What is Bischofite?
More than 200 million years ago, an ancient seabed formed near Poltava, a city in Ukraine. At the bottom
of the seabed was a layer of mixed salts called Bischofite . The main component of most Bischofite (about
96 percent) is magnesium.

8. • Solution mining consists of drilling
holes into an ore body and pumping
heated water into the deposit.
• The heated water dissolves carnallite
and brine, allowing them to be
pumped out through the holes.
• The pumped solution goes through
an evaporation process that
removes water and magnesium
chloride and leaves behind
potassium chloride and sodium
chloride.
