Properties of Chrome Ore:
Chrome ore, primarily consisting of chromite (FeCrO), is rich in iron, chromium, and oxygen. is a mineral that serves as the main source of chromium. Chromium is a critical element used in various industries.
Appearance: It usually appears as dark gray to black with a metallic luster.
Hardness: It's relatively hard, with a Mohs hardness of 5.5.
Density: High density, which makes it useful in heavy-duty industrial applications.
Mining and Production:
Mining Process:
Open-pit Mining: Suitable for deposits near the surface.
Underground Mining: Used for deeper deposits.
Ore Processing: Chrome ore is processed into ferrochrome (an alloy of chromium and iron) through smelting in an electric arc furnace. This is a crucial material in stainless steel production.
Applications:
1.Stainless Steel: Chromium gives stainless steel its corrosion-resistant properties. Nearly 80% of the world's chromium is used in this sector.
2.Refractories: Chrome ore is used to manufacture heat-resistant bricks and lining for furnaces.
3.Chemical Industry: Used to produce chromium chemicals for pigments, tanning leather, and anodizing aluminum.
4.Foundry Sand: Processed chrome ore is used in mold-making during metal casting.

Main Application
Chromite Sand in the foundry industry
Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. Its high thermal conductivity gives it good chilling properties, low thermal expansion gives rise to good dimensional stability. Its basicity being close to neutral allows the use of a wide range of resin bonding systems and inorganic binders, it has a high refractoriness and a broad sieve distribution.
Chromite Sand in the steel industry
In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles.
Chromite Sand in the glass industry
When ground to a fine flour, Chromite Sand is used for the production of green glass beverage containers.

Black Foundry Chromite sand is a high-quality sand primarily composed of chromite (FeCrO), a naturally occurring mineral that is rich in iron and chromium. It is widely used in the foundry industry for manufacturing molds and cores due to its excellent refractory properties, high melting point, and ability to withstand thermal shock. This makes it ideal for casting ferrous and non-ferrous metals, particularly in high-temperature processes. Chromite sand's low thermal expansion and good wear resistance also make it suitable for steel and alloy casting.
Additionally, its resistance to chemical reactions at high temperatures enhances the durability and precision of molds, providing superior surface finishes for metal castings.
