India’s rapid industrialization and infrastructure growth have consistently increased the demand for base metals like zinc. Among the various forms of zinc, zinc ingots play a critical role in several sectors such as galvanization, die-casting, alloy production, and even pharmaceuticals. Starting a Zinc Ingots Manufacturing Business can be a highly profitable venture for entrepreneurs looking to enter the metal and materials industry.

Zinc is the fourth most widely used metal in the world after iron, aluminum, and copper. According to the International Lead and Zinc Study Group (ILZSG), global demand for zinc is expected to exceed 14 million tonnes by 2025. In India, the growth is fueled by the construction, automobile, and electrical industries. The good news? India has one of the largest zinc reserves in the world and a strong domestic refining infrastructure, offering both raw material availability and market access. If you’re aiming to launch a stable, scalable, and industrial business, the zinc ingots manufacturing business is a smart and strategic choice.

Business Overview of Zinc Ingots Manufacturing

Zinc ingots are refined solid forms of zinc that are typically 99.9% pure. These are produced through electrolysis or thermal processes and then cast into standard-sized ingots. These ingots are then used as a base material for:

• Galvanizing steel structures

• Zinc die-casting

• Making alloys like brass

• Battery components

• Pharmaceutical and cosmetic uses

Industrial Insight: Galvanizing accounts for nearly 50% of zinc consumption globally, making it the biggest downstream application.

1. Raw Materials and Sourcing

The major raw materials required include:

• Zinc concentrate or zinc oxide dust (primary or secondary sources)

• Coal or petroleum coke (for thermal process)

• Sulfuric acid (used in leaching for electrolytic zinc extraction)

• Flux and binders (for purification and casting)

India is home to large mining companies like Hindustan Zinc Ltd, making local sourcing feasible for MSMEs and mid-scale producers.

2. Manufacturing Process

There are two main processes for zinc ingot manufacturing:

a) Pyrometallurgical Process

Involves roasting, reduction, and smelting of zinc ore or oxide to extract molten zinc, which is then cast into ingots.

b) Electrolytic Refining

Zinc is extracted by leaching concentrate in sulfuric acid, followed by purification and electrolysis, producing high-purity zinc.

Note: The electrolytic process yields purer zinc but has higher setup costs.

3. Plant Setup and Machinery

For a small to medium-sized zinc ingots manufacturing business, the setup requires:

• Roaster and smelting furnace

• Electrolytic cell (if refining)

• Casting machine (ingot mold and conveyor system)

• Pollution control units (scrubbers, chimney, ash collector)

• Crucibles and ladles

• Testing and quality control lab

Investment Estimate: ?1.5 crore to ?5 crore for a medium-scale unit depending on automation level and production capacity.

4. Licensing and Legal Compliance

Since it involves heavy metal processing, several licenses and clearances are required:

• Udyam MSME Registration

• Factory License

• Consent to Establish and Operate (Pollution Control Board)

• GST Registration

• Hazardous Waste Handling Authorization

• Explosive/boiler license (if using thermal furnaces)

ISO 9001 and ISO 14001 certifications enhance credibility and environmental compliance.
