Bentonite
The Versatile Clay of Industry
Four grades of bentonite, each activated for its application
From API drilling-grade to foundry and pelletising binders — every batch is processed and tested to specification.
DRILLING-GRADE BENTONITE (API STANDARDS)
Maximum rheological performance under intense downhole pressure.
Our drilling-grade bentonite is engineered specifically for the demanding conditions of oil and gas exploration, water well drilling, and horizontal directional drilling (HDD). When added to drilling fluids, this premium sodium bentonite acts as an exceptional rheological modifier. It expands rapidly in water to build a highly structured, thixotropic suspension that carries heavy rock cuttings efficiently up to the surface.
Our processing focus centers on delivering high gel strength and excellent fluid loss control. It forms a thin, low-permeability filter cake along the borehole wall, effectively sealing porous geological formations. This structural barrier stabilizes the wellbore, balances hydrostatic pressures, and prevents expensive fluid loss into the surrounding earth.
Core Characteristics
- Strict compliance with API (American Petroleum Institute) and OCMA international standards.
- High swelling volume and rapid dispersion kinetics in freshwater matrices.
- Superior thixotropic properties to keep cuttings suspended when drilling stops.
- Low filter-cake thickness to minimize downhole friction and tool sticking.
Primary Applications
- Onshore and offshore oil and gas well drilling mud formulations.
- Horizontal Directional Drilling (HDD) and micro-tunneling operations.
- Water well drilling, geothermal exploration, and deep shaft sinking.
- Specialized fluid-stabilization slurries for civil engineering foundations
FOUNDRY BONDING BENTONITE
Preserving absolute dimensional accuracy through extreme thermal shock.
In high-temperature metallurgical casting, foundry greensand must hold its shape perfectly when slammed with molten iron, steel, or non-ferrous alloys. Our foundry-grade bentonite serves as an elite binding agent that wraps uniformly around silica sand grains. This creates a highly cohesive, robust mold structure that resists premature cracking, erosion, and thermal degradation during the pouring stage.
We offer both high-durability Sodium Bentonite (valued for its exceptional hot shear strength and thermal longevity) and Calcium Bentonite variants tailored for specialized cooling cycles. Our precise processing ensures the ideal balance of dry strength and green compressive strength. This gives the mold the flexibility to breathe out expanding gases while maintaining clean, flawless surface finishes on cast metal parts.
Core Characteristics
- High green compressive strength to prevent mold distortion during handling.
- Excellent thermal durability, allowing the sand mixture to be recycled and reused repeatedly.
- High hot shear strength to withstand the aggressive wash of heavy molten metal flow.
- Optimal moisture retention window to ensure predictable sand mulling properties.
Primary Applications

- Heavy machinery foundries producing cast iron valves, gears, and structural frames.
- High-precision steel and alloy casting for aerospace and industrial hardware.
- Protective refractory binder configurations and custom foundry sand pre-mixes.
CIVIL ENGINEERING & PILING BENTONITE
Uncompromising structural containment and hydrostatic barrier engineering.
Our civil engineering-grade bentonite is specifically processed to handle challenging ground stabilization, piling, diaphragm wall construction, and environmental containment projects. When mixed with water, it creates a dense, viscous slurry that exerts continuous hydrostatic pressure against trench walls. This temporary hydraulic shield prevents fragile soils from caving in before concrete can be poured.
Furthermore, its high montmorillonite content makes it an exceptional sealing material for environmental lining. It acts as an impermeable geological barrier when blended into soil cements, effectively sealing landfill bases, water reservoirs, and industrial ponds to prevent hazardous chemicals or wastewater from leaching into local groundwater systems.
Core Characteristics

- Landfill liners, industrial waste containment caps, and artificial pond seals.
- Grouting slurries for structural soil stabilization and underground dam construction.
ULTRA-ABSORBENT CONSUMER & CAT LITTER BENTONITE
Natural moisture retention and structural clumping kinetics.
Our consumer-grade sodium bentonite is processed to achieve maximum liquid absorption capacity and immediate clumping mechanics. Mined from our finest natural reserves, this clay features an expansive internal surface area that traps moisture instantly upon contact. This rapid absorption triggers localized swelling, locking the liquid into hard, tightly bound, and easy-to-remove clumps before it can spread to the rest of the tray.
Our processing plants use advanced dust-control systems to ensure the granulated material is exceptionally clean and structurally sound. This prevents the grains from breaking down into fine airborne dust during transport or use, making it a premium raw material for global pet care brands, hygiene product manufacturers, and chemical blending operations.
Core Characteristics
- Instantaneous clumping kinetics that form tight, durable, non-breaking lumps.
- High liquid absorption value, drawing in multiple times its own dry weight.
- Advanced de-dusting processing to ensure an ultra-clean, dust-free final product.

- Carrier matrices for household cleaning chemicals and moisture-retention powders.
- Agricultural soil-conditioning aggregates designed to lock in root moisture.
IRON ORE PELLETIZATION (IOP) BENTONITE
Optimizing metallurgical processing through high green pellet strength.
In modern steel manufacturing, fine iron ore concentrates must be rolled into uniform spherical pellets before they can be fed into blast furnaces or direct-reduction plants. Our IOP-grade sodium bentonite serves as a highly efficient structural binder for this pelletization process. Even when added in minute percentages, it spreads evenly across the iron ore fines, creating a powerful adhesive bond.
Our material ensures that the wet "green" pellets possess the structural elasticity needed to withstand rapid conveyor handling without cracking. More importantly, it maintains its binding integrity during high-temperature pre-heating and drying phases, preventing the pellets from shattering into fine dust and blocking the air passages inside the furnace.
Core Characteristics
- High green pellet drop number resistance to prevent breakage on drop transfers.
- Superior dry crushing strength to handle heavy stacking loads in storage yards.
- Low overall dosage requirements, helping to minimize silica impurities in the final steel melt.
- Excellent water-absorption control to ensure smooth pellet rolling dynamics.
Primary Applications

- Direct Reduced Iron (DRI) processing plants and global steel mills.
- Metallurgical blending facilities and bulk sintered-ore processing hubs.
- Integrated steel manufacturing plants.
REFINING & PURIFICATION BENTONITE (BLEACHING CLAY)
Achieving pristine chemical purity through advanced surface adsorption.
Purification-grade bentonite—often highly activated via precise thermal or acid treatment—is engineered specifically for the decolorization, clarification, and purification of industrial oils, fats, and bio-fuels. The primary challenge for oil refineries is removing unwanted pigments (like chlorophyll and carotenoids), residual gums, and trace heavy metals without altering the beneficial properties of the oil. Our highly porous activated bentonite features a massively expanded internal surface area that physically traps these impurities.
By maximizing the cation exchange capacity, our bleaching clay targets and isolates oxidation products and chemical contaminants. This results in an exceptionally clear final liquid that meets international food-grade and industrial safety standards. Whether integrated into large-scale edible oil refining lines or high-volume petrochemical processing plants, this material maximizes filtration efficiency and prevents color reversion during storage.
Core Characteristics
- Chemically treated to optimize surface porosity and macro-pore structure.
- Superior adsorption capacity for pigments, trace metals, and volatile oxidation markers.
- Excellent filtration speed, preventing the clogging of automated filter presses.
- Low oil retention profile, minimizing product loss within the discarded press cake.
Primary Applications
- Vegetable oil refining plants (soybean, palm, sunflower, and cottonseed oils).
- Biodiesel purification and bio-fuel pre-treatment manufacturing setups.
- Petroleum lubricant reclamation, paraffin wax bleaching, and mineral oil recycling.
- Industrial wastewater treatment facilities focusing on surfactant and dye removal.
CERAMIC & SANITARYWARE BENTONITE
Enhancing green strength and plasticity in advanced clay vitrification.
In high-end ceramic and tile manufacturing, the raw clay body must possess excellent elasticity to take detailed shapes under heavy hydraulic presses without cracking. Our ceramic-grade white bentonite acts as an elite plastifier and binding additive. Even when blended in minute percentages (typically 1% - 3% ), it fills the microscopic gaps between quartz and feldspar grains, significantly boosting the plastic workability of the raw slip.
Furthermore, our material drastically improves the "green strength" (pre-fired strength) of fragile unfired tiles, porcelain tableware, and large sanitaryware molds. This prevents structural deformation, chipping, and hairline fractures during handling and drying. Because we selectively mine and process low-iron, low-titanium bentonite reserves, our product preserves the bright white or translucent fired profile demanded by premium porcelain brands.
Core Characteristics
- Exceptionally high plasticity index to facilitate smooth extrusion and molding.
- Drastically increases dry bending strength (green strength) in ceramic bodies.
- Low iron ( Fe_2O_3 ) and titanium ( TiO_2 ) chemistry to prevent firing discoloration.
- Functions as an excellent anti-settling suspending agent in ceramic glaze slips.
Primary Applications
- Vitrified tile and premium porcelain tile manufacturing plants.
- Large-scale sanitaryware production lines (sinks, toilets, and architectural ceramics).
- High-end tableware, fine china, and ornamental stoneware factories.
- Specialized electrical porcelain insulators and technical ceramic components.
PAPER RETENTION & PULP GRADE BENTONITE
Optimizing fiber bonding and drainage speeds in high-speed paper machines.
Modern, high-speed paper manufacturing lines require highly precise chemical control to manage pulp drainage and fine particle retention. Our paper-grade sodium bentonite is micronized down to ultra-fine particle sizes and acts as a high-performance micro-particle retention aid. When introduced into the paper pulp slurry alongside cationic polymers, it creates a powerful ionic bond that clusters fine fibers, wood fillers, and pigments together.
This microscopic clustering allows water to drain rapidly through the forming wire mesh, significantly increasing the mechanical drainage speed of the paper machine. By keeping expensive mineral fillers bound to the paper sheet rather than washing away into the wastewater loop, it lowers chemical costs, enhances the opacity and smoothness of the paper, and reduces the environmental footprint of the mill's effluent treatment system.
Core Characteristics
- Micronized particle distribution optimized for rapid ionic interaction in pulp loops.
- Outstanding Cation Exchange Capacity (CEC) to attract and bind positively charged fibers.
- Significantly increases dewatering and drainage velocity on the forming table.
- Chemically clean mineral profile, completely free of abrasive crystalline grits.
Primary Applications
- High-speed A4 copy paper and fine writing paper production mills.
- Duplex board, packaging containerboard, and kraft paper manufacturers.
- Specialized coated paper, newsprint, and industrial tissue processing facilities.
- Closed-loop white water clarification systems in the pulp and paper industry.
PHARMACEUTICAL, COSMETIC & PURE FOOD GRADES
Ultra-purified, microbiologically sterile mineral stabilization.
Beyond heavy industrial plants, bentonite serves as an indispensable, non-toxic excipient and texturizer in human health and personal care products. Our pharmaceutical and cosmetic grade bentonite undergoes intensive water-washing, structural purification, and heat sterilization to completely eliminate coarse quartz grit and heavy metals. This results in an ultra-fine, velvety powder that fully complies with international pharmacopeia and regulatory purity standards.
In pharmaceutical applications, its high absorption capacity makes it an excellent binder for compressing solid tablets and an ideal suspending agent for stabilizing liquid suspensions or medicinal creams. In the cosmetics sector, its high ion-exchange capability allows it to actively draw out impurities, sebum, and toxins from the skin, making it the premier foundational element for luxury skincare masks, thick lotions, and personal care formulations.
Core Characteristics

ELECTRICAL GROUNDING & BACKFILL BENTONITE
Permanent moisture retention for low-resistance earthing systems.
Electrical earthing and grounding systems require a stable, highly conductive surrounding environment to safely dissipate fault currents deep into the earth. Standard soil often dries out, shrinks, and loses contact with grounding electrodes, causing dangerous spikes in electrical resistance. Our specialized earthing-grade sodium bentonite is processed to serve as a permanent, low-resistance backfill material for grounding pits and trenches.
When poured around an earthing rod and mixed with water, this bentonite expands tightly into all surrounding rock fractures and soil voids, creating a solid, permanent contact surface. Because sodium bentonite retains up to several times its dry weight in water, it holds moisture long-term, maintaining a highly conductive, low-impedance connection even during intense summer droughts. Furthermore, its alkaline nature forms a protective coating around earthing conductors, preventing corrosion and extending the lifespan of the entire grounding network.
Core Characteristics
- Maintains low electrical resistivity even under varying climatic conditions.
- Exceptional water-retention capacity, keeping the root earthing zone moist long-term.
- Expands deeply to form a highly compact, non-shrinking structural fill.
- Non-corrosive, alkaline chemistry that actively protects copper and galvanized steel electrodes.
Primary Applications
- High-voltage electrical substations, power plants, and transmission line towers.
- Telecommunication towers, data centers, and lightning protection earthing pits.
- Oil and gas pipelines, storage tank farms, and petrochemical facility grounding.
- Commercial building infrastructure, solar power farms, and wind turbine installations.
