An ore of chromium
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.
About two thirds of chrome ore deposits are located in South Africa We bring the raw material reliably quickly and efficiently from Mozambique to the buyers destination We can guarantee you the highest product quality with the best service in procurement and logistics
Refractory Chrome Ore Lumpy
Top quality Chrome Ore Lumpy manufacturer (south africa).The chromite sand is a product of south africa natural chromite ore after crushing and sieving, and its main chemical composition is Cr2O3.
*Melting point of 2150°C
*Good thermal conductivity
*Good resistance to thermal shock
*Excellent resistance to metal penetration or burn-on
South africa chrome ore lumpy is a highly fireproof sharpener for moulds and cores. Originally from South Africa. The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.
