Limestone
About the Product
Limestone is a naturally occurring sedimentary rock, composed primarily of calcium carbonate (CaCO₃). At Rupsha, we source high-purity limestone known for its uniform composition, low silica content, and superior structural properties. Our limestone is processed and screened to meet industrial-grade specifications required in high-temperature environments and chemical applications.
Use Cases
-
Cement Clinker Production: Acts as the key raw material, contributing lime (CaO) to the clinker formation process.
-
Steel Manufacturing: Used as a fluxing agent in blast furnaces to remove impurities such as silica and phosphorus from molten iron.
-
Construction Industry: Crushed limestone is widely used as a base material in road construction, concrete, and railway ballast.
Dolomite
About the Product
Dolomite (CaMg(CO₃)₂) is a versatile mineral that contains calcium and magnesium carbonates. Our high-quality dolomite is known for its consistent grain size, low iron content, and high MgO concentration. It is an essential component in various industrial processes where both calcium and magnesium are required.
Use Cases
-
Iron & Steel Industry: Acts as a flux to remove impurities and stabilize the slag during steelmaking processes.
-
Glass Industry: Enhances durability, chemical resistance, and strength in flat and container glass manufacturing.
-
Fertilizers and Refractories: Used in producing agricultural lime and refractory bricks due to their thermal stability.
Quick Lime
About the Product
Quick Lime, or burnt lime, is produced by calcining limestone at high temperatures to remove carbon dioxide. The result is highly reactive calcium oxide (CaO), which we deliver fresh to preserve reactivity and effectiveness. Our quick lime is tailored for chemical and metallurgical industries with high purity and low residue.
Use Cases
-
Steel & Metallurgical Industry: Used for desulphurization and to control slag chemistry during steelmaking.
-
Water Treatment: Helps in pH regulation, neutralization of acids, and softening of water.
-
Paper & Sugar Industry: Used in pulp processing and sugar purification as a clarifying agent.
Flourspar
About the Product
Flourspar is a mineral composed of calcium fluoride (CaFâ‚‚), available in multiple grades. We supply both acid-grade (97%+ CaFâ‚‚) and metallurgical-grade (60–85% CaFâ‚‚) flourspar tailored to the steel, chemical, and ceramic sectors. Our product is free-flowing, low in silica, and packed with care to prevent moisture damage.
Use Cases
-
Steel Industry: Used as a flux to lower the melting point of raw materials and improve fluidity in slag.
-
Aluminum & Glass Manufacturing: Acts as a stabilizing agent in high-temperature production processes.
-
Chemical Industry: Key ingredient in the production of hydrofluoric acid, which is used in refrigerants and aluminum refining.
Iron Ore
About the Product
Iron ore is the principal raw material used in steelmaking. We supply calibrated lumps and fines with high Fe content (typically 58–65%) and minimal gangue material. Our ore is sourced from reputable mines and tested for consistent physical and chemical characteristics, ideal for sintering and pelletization.
Use Cases
-
Blast Furnace Operations: Used to produce molten iron through reduction with coke.
-
Sintering Plants: Crushed fines are agglomerated into sinter for furnace use.
-
Pellet Manufacturing: Processed into pellets for energy-efficient and uniform steelmaking.
Pellets
About the Product
Iron ore pellets are spherical balls made from iron ore fines, enriched with fluxing agents and binders, and indurated at high temperatures. These offer uniform size, low impurities, high mechanical strength, and better metallurgical performance compared to lumps.
Use Cases
-
Direct Reduced Iron (DRI) Plants: Preferred feed due to low gangue content and high reducibility.
-
Blast Furnaces: Provide better permeability, productivity, and reduce fuel consumption.
-
Cleaner Steel Production: Lower emissions, reduced slag volume, and efficient heat transfer.
Clinker
About the Product
Clinker is the key intermediate product used in manufacturing Portland cement. It is produced by heating a blend of limestone and clay in a rotary kiln, forming hard, nodular materials rich in calcium silicates like Alite and Belite. At Rupsha Minerals, we supply high-quality clinker with excellent grindability and chemical stability, suitable for both domestic use and global trade.
​
Our clinker supports various cement types, including sulfate-resistant, low-heat, white, low-alkali, and BCT-based cements.
Use Cases
-
Cement Production: Ground with gypsum and other additives to produce OPC and blended cements.
-
Infrastructure Projects: Ideal for highways, buildings, and large-scale civil works.
-
Specialized Cement Types: Used in white cement, low-heat, and sulfate-resistant formulations.
-
Global Trade: Highly durable and easy to store, making it suitable for bulk export.
Coke
About the Product
Metallurgical coke is a carbon-rich solid derived from bituminous coal through destructive distillation in coke ovens. Our coke is high in fixed carbon (85%+), has low sulfur and moisture content, and excellent crushing strength, making it ideal for metallurgical use.
Use Cases
-
Blast Furnace Ironmaking: Serves as both a fuel and reducing agent in converting iron ore to pig iron.
-
Foundries: Maintains furnace temperature and ensures a clean melt during casting.
-
Alloy & Ferroalloy Plants: Used in smelting non-ferrous metals and maintaining reduction reactions.
Gypsum (Natural & Synthetic)
About the Product
Gypsum (CaSOâ‚„·2Hâ‚‚O) is a soft sulfate mineral available in natural and synthetic (from FGD plants or chemical processing) forms. We supply finely processed gypsum tailored for construction, agriculture, and industrial use.
