Require a Custom Lead Alloy or Specific Elemental ppm?

Our Dewas refining facility formulates custom lead alloys controlled with Antimony (Sb), Tin (Sn), Calcium (Ca), Copper (Cu), and Arsenic (As). Batch-wise Certificate of Analysis (CoA) provided with each dispatch.

Products

Refined metal, made to specification.

All products & services

Refined Lead Ingots

Recovered lead, refined and cast into ingots of uniform weight and shape, cooled, stamped and batch-coded so every unit remains traceable to its production record.

Lead Alloys — Customised Grades

Where a customer's application calls for a specific composition, the refining route is tailored to achieve the required alloy grade rather than a single standard product.

Antimony Lead Alloys

Manufactured through controlled refining to deliver consistent chemical composition and mechanical strength. By precisely controlling antimony content, we produce alloys for demanding industrial applications.

Services

Our Services

Environmentally compliant lead recycling operations
01

Environmentally compliant lead recycling

End-to-end recycling of used lead-acid batteries and lead-bearing scrap under statutory, environmental and safety regulations.

Customised alloy development and refining
02

Customised alloy development

Refining routes adapted to reach the purity or alloy composition a specific application requires.

Used lead-acid battery scrap sourcing and processing
03

Scrap sourcing & processing

Sourcing, assessment and processing of lead-bearing material from authorised suppliers, aggregators and corporate generators.

Secure disposal and management of hazardous by-products and slag
04

Secure disposal of hazardous by-products

By-products routed through authorised recyclers and disposal channels in line with regulatory requirements.

The manufacturing journey

From waste material to refined metal.

Nine controlled stages between a scrapped battery and a stamped, batch-coded ingot.

Recovered lead-bearing scrap awaiting inspection
01/09

Raw Material Collection & Inspection

Material arrives with a history. We establish it before anything else.

  • Collection of used lead-acid batteries and lead scrap from authorised sources
  • Incoming material inspection and weighment
  • Verification of compliance with hazardous waste regulations

Objective — Ensure safe, compliant and traceable raw material sourcing.

02/09

Battery Breaking & Segregation

One object becomes four material streams.

  • Mechanical breaking of batteries
  • Separation into lead metal (grids and terminals), lead paste, plastic components and electrolyte

Objective — Efficient segregation of recoverable materials.

Filter presses at the Effluent Treatment Plant
03/09

Acid Neutralisation & Treatment

The part of recycling nobody photographs, and the part that matters most.

  • Battery acid is neutralised using approved chemicals
  • Treated effluent sent to the Effluent Treatment Plant (ETP)
  • Neutralised residue disposed of as per regulatory norms

Objective — Prevent environmental contamination and ensure zero liquid discharge.

Furnace charge and burner during smelting operation
04/09

Smelting & Melting

Controlled heat. The only place on this site where things glow.

  • Lead paste and metallic lead are charged into furnaces
  • Controlled high-temperature smelting converts material into molten lead
  • Fluxes are added to remove impurities
  • Slag is separated and handled safely

Objective — Recover molten lead efficiently with minimal loss.

Refining & Purification

Purity is not found. It is engineered, one impurity at a time.

  • Molten lead undergoes refining to remove residual impurities
  • Refining process tailored to achieve required purity or alloy composition
  • Continuous quality checks during refining

Objective — Achieve customer-specified lead purity and alloy grades.

Automated ingot casting machine operating in the plant
06/09

Casting & Ingot Formation

Liquid becomes inventory.

  • Refined lead is cast into ingots or blocks
  • Automated moulding ensures uniform weight and shape
  • Ingots are cooled, stamped and batch-coded

Objective — Produce standardised, market-ready lead products.

Quality Control & Testing

A batch leaves with a chemistry, not an assurance.

  • Chemical analysis of lead content and impurities
  • Physical inspection of ingots
  • Batch-wise quality documentation

Objective — Ensure consistent quality and regulatory compliance.

08/09

Pollution Control & Waste Management

What we do not send out is as engineered as what we do.

  • Air emissions controlled through bag filters and chimneys with prescribed stack height
  • Slag and dust disposed of through authorised recyclers
  • Plastic sent for recycling
  • Continuous environmental monitoring

Objective — Maintain strict environmental and safety standards.

Lead ingots stacked and stored in dispatch bay
09/09

Packaging, Storage & Dispatch

The material leaves to begin its next working life.

  • Ingots packed as per customer requirement
  • Secure storage in designated areas
  • Dispatch through approved logistics channels

Objective — Safe handling and timely delivery.

Quality

Quality You Can Verify

From incoming material to finished ingot, quality should be traceable — not assumed.

Every batch has a story. A QR code on the Certificate of Analysis linking to a secure batch-verification page is planned as a future capability.
