Directly mined, hydro-washed, and rotary kiln-dried in Bhuj (Kutch). Engineered with controlled kiln moisture (0.15%–0.25%), deslimed clay (<0.18%), and custom multi-deck sieve grading (AFS 25 to 65) for India’s tier-1 foundries, glassworks, and core manufacturers.
Headquartered in the mineral-abundant basin of Bhuj, Kutch (Gujarat), Gujarat Minerals is dedicated solely to the extraction, washing, drying, and multi-deck sieve classification of premium Silica Sand (SiO₂ > 99%).
We specialize in fulfilling the stringent particle distribution and grain fineness requirements (AFS 25 to 65) needed by ferrous and non-ferrous foundries, container glass plants, and high-spec construction formulators. With direct road connectivity across 9+ Indian states and proximity to Kandla and Mundra deep-water ports, we ensure prompt, uninterrupted raw material supply.
Triple-washed and kiln-dried high-purity quartz processed strictly to your plant’s grain fineness (AFS), chemical assay, and mesh tolerances.
Rotary kiln-dried (0.15%–0.25% moisture) sub-angular silica sand with deslimed clay (<0.18% max), 0.00% PAN fines (certified spec), and sintering point >1,650°C for grey iron, ductile SG iron, and steel castings.
From raw mineral bed to your furnace bay: our 6-stage quality pipeline delivers controlled low moisture (0.15%–0.25%) and calibrated grain fineness.
Raw silica quartz deposit selection in Kutch ensuring baseline SiO2 purity above 99% with minimal overburden contamination.
High-pressure multi-stage hydro-cyclone washing to strip clay fines (<0.18% max), followed by cross-belt magnetic separation to eliminate tramp iron.
Continuous rotary kiln drying reduces residual moisture to controlled levels of approximately 0.15%–0.25%, eliminating paid water freight and reducing moisture-related gas defect risks.
Vibratory screening across calibrated ASTM mesh decks (10 to 270 screen sizes) to isolate exact AFS numbers (AFS 25-28, 40-45, 50-55).

Answers to common questions regarding minimum order quantities, sieve testing certificates, delivery timelines, and bulk freight options.
Mined in Kutch, washed and rotary kiln-dried with certified granulometric sieve curves and chemical assays.
Rotary kiln-dried sub-angular quartz sand engineered for high-integrity iron and steel core-making with 98.5% SiO₂ refractoriness.
Triple-washed and precision-screened silica quartz filter media with 98.21% SiO₂ purity and zero leaching in multi-media water filtration.
Ultra-pure low-iron quartz sand for container and solar PV glass, featuring >99.4% SiO₂ with Fe₂O₃ strictly below 220 ppm.
Unwashed pit and river sands contain micro-fines and moisture that absorb expensive liquid resin. Kiln-dried sand with 0.15%–0.25% moisture and <0.20% clay drops binder consumption safely down to 1.2%.
*Estimated simulation. Low-ADV silica can reduce binder consumption by approximately 15%–20%, depending on the foundry's binder system and process parameters. Actual savings vary with binder chemistry, sand-to-metal ratio, casting process, and plant operating conditions.
Compiled from continuous multi-lot Ro-Tap sieve assays and XRF chemical spectrometry at our Bhuj facility. Designed for consistent batch-to-batch quality through controlled processing and laboratory verification.
Zero Dead Water Weight: Purchasing damp sand means paying freight for dead water. Controlled kiln drying (0.15%–0.25%) reduces moisture-related gas defect risks during high-temperature pours.
Binder Efficiency: Micronized clay acts like a sponge, absorbing binder. Our deslimed quartz allows chemical binder to bond directly, offering potential binder consumption reductions of approx. 15%–20% depending on process conditions.
Maximum Permeability: Dead fines clog mould interstitial pores and cause gas pinholes. Complete dust stripping (0.00% PAN fines certified spec) delivers clean gas evacuation and zero mixer gumming.
High Sintering Resistance: Sintering point exceeding 1,650°C withstands iron and steel pours, reducing burn-on and simplifying fettling operations.

| Parameter / Test | Gujarat Minerals Standard | Standard Industry Sand | Commercial & Quality Impact |
|---|---|---|---|
Rotary Kiln Moisture Defect Protection | 0.15% – 0.25% | 0.50% – 4.00% (Raw / Wet Sand) | Zero dead water freight. Controlled low moisture reduces moisture-related gas defect risks. |
Clay Content (A.F.S. Slimes) Resin Savings | < 0.18% Max (Deslimed) | 0.50% – 1.00% (Standard River Sand) | Prevents binder theft. Low-ADV deslimed sand can reduce binder consumption by approx. 15%–20% depending on process parameters. |
PAN Dead Dust (-140M & Pan) High Permeability | 0.00% (Certified Spec) | 1.00% – 3.50% (Unwashed Quartz) | Maximum mould venting permeability. Avoids mixer gumming and prevents core gas entrapment. |
Target Sieve Concentration Core Strength | 92.00% – 98.00% | 70.00% – 80.00% (Broad Distribution) | Concentrated across 3–4 adjacent screens. Yields dense, uniform core packing with superior tensile strength. |
Grain Fineness Versatility Custom Spec | AFS 25 to AFS 65 (Custom) | Fixed Single-Mesh Grades | Custom-calibrated multi-deck screen decks configured strictly to your foundry's casting metallurgy. |
