Chrome Concentrate is a high-grade material derived from chrome ore, primarily used in the metallurgical industry for producing ferrochromeâ??a key component in stainless steel manufacturing. With a high chromium-to-iron ratio and low impurities, Chrome Concentrate is essential for enhancing the corrosion resistance, hardness, and durability of steel and other alloys.
Key Features:
1. High chromium content (Cr2O3)
2. Low impurities such as silica and alumina
3. Consistent particle size distribution
4. Ideal for ferrochrome and stainless steel production
Applications:
1. Stainless steel production
2. Alloy casting
3. Chemical and refractory industries
Available in various grades to meet specific industry requirements, Chrome Concentrate ensures optimal performance for metallurgical processes.

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.
Zinc ore is most commonly found as zinc carbonate (ZnCO3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that have a vitreous or pearly luster and are typically dirty brown or grey in colour.
Nigeria is richly blessed with large deposits of Zinc ore in Ebonyi and Benue state. We can export top quality of this product in 1000-1500MT every month.
