Zinc ash

1. Specification

• Zinc Content: You’ll usually see between 50% and 60% zinc—enough to make it worth processing.

• Moisture: We keep it below 8%. If it’s too wet, you end up paying extra just to dry it off.

• Composition: It’s mainly zinc oxide (ZnO), with just a pinch of chlorides and trace metals like lead (under 0.5%) or cadmium (under 0.1%).

• Particle Size: It’s ground down to about 50–200 microns, which means it leaches or melts quickly when you process it.

• Packaging Weights:

  • 25 kg bags—easy to carry by hand.

  • 50 kg bags—stackable on a pallet for forklifts.

  • 1 MT bulk bags—perfect for larger orders.

  • If you need something custom, just let us know.

2. Why Choose Us

• Experience & Trust: We’ve been in this business for more than ten years. We understand what galvanizers, die‐casters, and chemists need because we work with them every day.

• Transparent Lab Reports: Every shipment comes with a clear ICP or XRF lab report so you know exactly how much zinc, moisture, and any trace metals are in that batch. That way, when it arrives at your plant, there are no unwelcome surprises.

• Commitment to Sustainability: By recycling zinc ash instead of sending it to landfill, you save on mining costs and reduce environmental impact. We’re proud to help you turn what was once scrap into something valuable.

• Responsive Support: Have a question about grades, samples, or shipping? We usually get back to you within 24 hours. We’ll walk you through picking the right blend and arranging logistics.

3. Key Applications

• Galvanizing Steel: Once you refine the zinc ash, you can melt it back into hot‐dip galvanizing lines. Builders and auto makers rely on that shiny, rust‐resistant finish.

• Die‐Casting Alloys: Clean zinc from ash blends perfectly into die‐cast alloys. Whether you make car parts or electronics housings, consistent zinc supply is crucial.

• Chemical & Pharmaceutical Uses: From zinc chloride to ZnO powder, these products are catalysts and ingredients for everything from ointments to industrial chemicals.

• Rubber & Paint Additives: A little zinc oxide goes a long way in improving rubber curing and making paint more corrosion‐resistant.

4. Quality Assurance

• Batch Testing: Before any shipment leaves our yard, we sample it and run either ICP or XRF tests. If zinc is under 50% or moisture is over 8%, it doesn’t go out.

• Independent Verification: To stay honest, we randomly send samples to an outside lab. That extra check makes sure our in‐house tests stay on point.

• Traceability: Every bag or bulk container has a batch number, an assay certificate, and a production date. You can trace exactly where it came from and when.

• Continuous Improvement: We regularly talk to the refineries that process our ash, tweaking how we collect and store it to minimize contamination and get you the best yield.

5. Flexible Logistics & Packaging

• Shipping Options:

  • Domestic: We can deliver DAP (Delivered at Place) right to your factory or warehouse anywhere in India.

  • International: We ship CIF (Cost, Insurance, Freight) or FOB from Mundra Port—our freight partners handle customs and onward delivery.

• Packaging Choices:

  • 25 kg bags: Perfect for small labs or pilot projects.

  • 50 kg bags: Standard palletized setup for forklift handling.

  • 1 MT bulk bags (FIBC): For larger quantities, each comes with a moisture‐barrier liner.

  • Drums/IBCs: Available if you need very small or specialized batches.

• Moisture‐Proof Sealing: All bags and bulk containers come with strong liners or seals so the ash stays dry—even in monsoon season.

• Just‐In‐Time Delivery: Need a regular weekly or daily top‐up? No problem. We schedule shipments to match your refinery’s feed schedule so you never run out—or pay rush charges.
