Product Description
Chrome
ore specifications vary based on its intended use, but generally
include parameters like Cr2O3 content, SiO2, Al2O3, MgO, and
Cr:Fe ratio, with metallurgical grade ore requiring a minimum of
*0% Cr2O3 and a specific Cr:Fe
ratio.
Here's
a more detailed breakdown of chrome ore
specifications:
Key
Parameters and Typical
Specifications:
Cr2O3
(Chromium Oxide):
This is
the primary indicator of chrome ore quality, with higher Cr2O3
content generally indicating higher
quality.
Metallurgical Grade: Minimum *0%
Cr2O3.
Refractory Grade: Can vary, but often has a
high Al2O3 content.
SiO2
(Silica):
Low
silica content is desirable, especially for metallurgical
applications, as silica can negatively impact ferrochrome
production.
Al2O3
(Aluminum Oxide):
High
aluminum content is characteristic of refractory grade
ore.
MgO
(Magnesium Oxide):
Also a
factor in ore quality, with varying acceptable levels depending
on the intended use.
Cr:Fe
Ratio (Chromium to Iron Ratio):
A
crucial indicator of ore quality, with a higher ratio generally
indicating better ore.
Metallurgical Grade: Typically requires a Cr:Fe
ratio of at least 2.*5:1.
Other
Impurities:
Phosphorus (P) and Sulfur (S) are undesirable
impurities and are typically specified to be below certain
limits.
Moisture:
Moisture content is also a factor, with a
typical maximum limit of 7%.
Size:
Ore
size is also a factor, with specifications often including the
percentage of ore that passes through a certain sieve
size.
Grades
of Chrome Ore:
Metallurgical Grade: Used in the production of
ferrochrome, a key ingredient in stainless steel and other
alloys.
Refractory Grade: Used in the production of
refractory bricks and other heat-resistant
materials.
Chemical Grade: Used in the production of
various chemicals and pigments.
Foundry
Grade: Used in the production of foundry
sand.
