Chemical
Analysis as per our standards
Iron
as Fe - Iron Oxide Fe2O3
As a commercial mineral Iron Ore often also contains small amounts of
the following:
Silica
as Si - Silicon Dioxide SiO2 :
Silica
occurs commonly in nature as sandstone, silica sand or quartzite and
ores. Method of analysis: -Spectrophotometry*
Aluminum
as Ag - Aluminum Oxide Al2O3 :
Aluminium
oxide is an amphoteric oxide of aluminium with the chemical formula
Al2O3. It is also commonly referred to as alumina in the mining,
ceramic and materials science communities. Method of analysis:
-Titrimetry (fluorine method)
Titanium
as Ti - Titanium Dioxide TiO2 :
Titanium
dioxide, also known as titanium(IV) oxide or titania, is the
naturally occurring oxide of titanium, chemical formula TiO2. Method
of analysis: -Spectrophotometry*
Magnesium
Mg - Magnesium Oxide MgO
Magnesium
is a white solid mineral that occurs naturally as periclase and is a
source of magnesium. Method of analysis: -Spectrophotometry*
Mamganese
Mn - Manganese Oxide MnO
Manganese
is a chemical element that has the symbol Mn and atomic number 25.
It is found as the free element in nature, often in combination with
iron, and in many minerals. Method of analysis: Spectrophotometry*
Sulfur
S - Sulfur dioxide SO2 (also sulphur dioxide)
Sulphur
is the chemical compound with the formula SO2. This important gas is
the main product from the combustion of sulfur. Method of analysis: Gravimetry*
Calcium
as Ca - Calcium oxide CaO
Calcium
commonly known as lime. Method of analysis: Spectrophotometry*
Loss
On Ignition - LOI
Whilst
it is desirable to have low contaminant levels of the elements
mentioned above, it is considered the opposite for an LOI measure.
Essentially, the LOI is a measure of the water content of the ore,
which evaporates when the ore is fed into a blast furnace. A typical
iron ore analysis should include an LOI determination at 1000 deg. C,
normally undertaken by Thermogravimetric Analyser (TGA).
