About Chromite Sand
Production
Chromite is a crystalline mineral composed primarily of FeO and Cr₂O₃ compounds. It is represented by the chemical formula of FeCr₂O₄. It is an oxide mineral belonging to the spinel group. Chromite Sand is mined from chromite-bearing rocks and beach sands and then crushed, screened and washed to remove impurities and achieve the desired grain size.
Uses of Chromite Sand
Used in the foundry industry for the manufacture of moulds and cores. Chromite Sand is applicable to all types of steels and very appropriate for Chrome Steel, Chrome-Nickel and Manganese Steel. Also used in the refractory sector to produce various chemicals and as a pigment.
Key Properties
Chromite Sand has high thermal conductivity and is resistant to thermal shock. It also has excellent resistance to metal penetration or burn on. It is resistant to slag attack and has high dimensional stability. It has a high melting point and it is also paramagnetic (slightly magnetic).

Chromite Sand FAQs
How is Chromite Sand used in the foundry industry?
In foundries, Chromite Sand is mixed with resin and other materials to create moulds and cores that shape molten metal into the desired forms. Its high melting point and resistance to thermal shock make it suitable for casting ferrous and non-ferrous metals, such as Iron, steel, and copper alloys. It is also an excellent ladle filler in continuous casting, used to prevent solidification of the molten metal, preventing blockages and ensuring a smooth flow of metal.
What is the difference between Chromite Sand and Silica Sand?
Other than the chemical composition (Chromite v Silica) and particle shape (Silica Sand particles have distinct, sharp edges as opposed to the more rounded edges of Chromite sand), Chromite Sand and Silica Sand have different properties which affects their use. The melting point of Chromite Sand and fire resistance temperature is much higher than Silica Sand. In fact, Silica Sand cannot withstand the pouring temperature of steel castings and its use would cause defects in the casting.
Silica Sand is used in ordinary sand cast iron casting but is unsuitable for use where it comes into contact with molten steel. Chromite Sand, on the other hand, is usually used for casting under high-temperature conditions where it does come into contact with molten metal liquid.
Chromite Sand particles are paramagnetic and heavier than Silica Sand particles allowing them to be separated from a mix of the two types of sands using electromagnets and density separation processes.
What is the difference between Chromite Sand and Silica Sand?
Chromite Sand is mainly used in:
-
Foundry applications for moulding and core-making in metal casting, especially in the automotive, aerospace, and heavy machinery sectors.
-
Refractory industries for producing heat-resistant linings and bricks for furnaces.
-
Glass manufacturing for making heat-resistant glass.
-
Chemical industries for producing Chromium chemicals.
