1-3mm Pyrite Granules

Casting Sulfur Adding, Water Treatment, Aquaculture

1. Casting Sulfur Adding

✅ Pain Point: Low sulfur content in cast iron → poor toughness, easy brittleness, 15-25% defective rate.

✅ Solution: 1-3mm pyrite granules (purity ≥90% FeS₂), uniform particle size, easy to mix with molten iron.

✅ Data & Result: Adds sulfur stably to 0.08-0.15% (optimal range for gray cast iron), reduces defective rate to <3%, improves casting wear resistance by 20%.

✅ Usage: Add 0.3-0.5kg per ton of molten iron, mix evenly before casting.

2. Water Treatment Filter Media

✅ Pain Point: Industrial wastewater with high heavy metals (Cr⁶⁺, Pb, Cd) & turbidity, failure to meet discharge standards.

✅ Solution: 1-3mm porous pyrite granules, large specific surface area (1.2-1.8 m²/g), strong adsorption capacity.

✅ Data & Result: Removes 98% of Cr⁶⁺ (from 100mg/L to <0.5mg/L), reduces turbidity to <5 NTU, service life up to 18-24 months.

✅ Usage: Fill filter tank with 50-80cm thickness, flow rate 8-12 m/h.

3. Aquaculture Bottom Improvement

✅ Pain Point: Aquaculture pond bottom hypoxia, excess organic matter, toxic hydrogen sulfide, low survival rate of aquatic products.

✅ Solution: 1-3mm slow-release pyrite granules, oxidizes harmful substances, balances pond pH (7.0-8.0).

✅ Data & Result: Reduces pond bottom ammonia nitrogen by 75%, increases dissolved oxygen by 30%, improves aquatic survival rate by 25-30%.

✅ Usage: 50-80kg per mu, spread evenly on pond bottom every 20-30 days.

3-8mm Pyrite Granules

Boiler Fuel, Soil Improvement, Counterweight Aggregate

1. Boiler Fuel

✅ Pain Point: Low-calorie fuel → high energy consumption, incomplete combustion, high emissions.

✅ Solution: 3-8mm pyrite granules (calorific value 2800-3200 kcal/kg), low ash content (≤8%), stable combustion.

✅ Data & Result: Saves 10-15% fuel cost compared to ordinary coal, reduces SO₂ emissions by 12% (with desulfurization equipment), combustion efficiency ≥92%.

✅ Usage: Mixed with coal (ratio 1:4-1:5) for industrial boilers, power plant boilers.

2. Soil Improvement

✅ Pain Point: Acidic soil (pH 3.5-5.5), poor fertility, low crop yield, heavy metal contamination.

✅ Solution: 3-8mm pyrite granules, slow oxidation to stabilize soil pH, immobilize heavy metals, supplement Fe and S.

✅ Data & Result: Adjusts soil pH to 6.5-7.0 (stable for 3-5 years), reduces Pb/Cd content by 60-70%, increases crop yield by 15-25%.

✅ Usage: 2-4 tons per hectare, plow 15-20cm deep into soil before planting.

3. Counterweight Aggregate

✅ Pain Point: Lightweight counterweight materials → unstable operation, poor load-bearing capacity.

✅ Solution: 3-8mm pyrite granules (bulk density 1.9-2.3 g/cm³), high specific gravity, uniform particle size, non-toxic and stable.

✅ Data & Result: Suitable for 50-500kg counterweight requirements, compressive strength ≥15MPa, no deformation after long-term use.

✅ Usage: Mixed with cement (ratio 3:1) for construction counterweights, mechanical equipment counterweights.

5-15mm Pyrite Granules

Kiln Combustion, Mine Backfilling, Bulk Counterweight

1. Kiln Combustion

✅ Pain Point: Kiln (cement, lime kiln) low combustion temperature, uneven heating, low production efficiency.

✅ Solution: 5-15mm pyrite granules, high calorific value, slow and stable combustion, supplementary heat.

✅ Data & Result: Increases kiln temperature by 80-120℃, improves production efficiency by 18%, reduces fuel consumption by 12%.

✅ Usage: Added to kiln raw materials, dosage 5-8% of total raw materials.

2. Mine Backfilling

✅ Pain Point: Mine goaf collapse risk, unstable backfilling materials, high cost.

✅ Solution: 5-15mm pyrite granules, high density, good stability, low water absorption (≤3%).

✅ Data & Result: Backfilling compactness ≥95%, prevents goaf collapse, reduces backfilling cost by 20% compared to traditional materials.

✅ Usage: Mixed with sand and cement (ratio 4:3:1) for mine goaf backfilling, filling thickness 50-100cm.

3. Bulk

✅ Pain Point: Large-scale equipment (cranes, ships) needs high-weight, stable counterweights, high cost of metal counterweights.

✅ Solution: 5-15mm large pyrite granules, bulk density 2.0-2.4 g/cm³, non-corrosive, low cost.

✅ Data & Result: Suitable for 1-10 tons bulk counterweight, cost 40% lower than steel counterweights, no rust, long service life.

✅ Usage: Filled into counterweight boxes, fixed with cement for large mechanical equipment, ship ballast.
