NEW DELHI (India CSR): Involute, a long-standing leader in powder metallurgy innovation, has unveiled a breakthrough suite of proprietary technologies aimed at solving one of India’s most urgent industrial and environmental challenges—the large-scale accumulation of iron ore tailings.
With more than one billion tons of tailings currently lying unused across the country, Involute’s solutions promise to convert this underutilized waste into high-value industrial materials.
Since iron ore is primarily used for iron and steel production, the following categories of processed ore materials are classified as tailings:
- Processed ores containing less than 50% iron,
- Processed ores in the form of dusts and fines (particle size below 50 microns), and
- A combination of both (i) and (ii) above.
Specifically Iron ore tailings are fine particles left after ore processing—occupy thousands of hectares across mining belts in India and pose significant environmental hazards due to their silica-, alumina-, and trace-element content. Traditionally considered a waste burden, these tailings now represent a major opportunity for value creation through Involute’s process-driven innovations.
INVOLUTE’s solutions are not only designed to address a critical national challenge, but they also create a strong impetus for deploying multiple Involute process technologies. These technologies enable significant value addition to otherwise classified “wastes,” while simultaneously facilitating the reclamation of vast tracts of land for vegetation, green cover, and other productive infrastructure developments.
Involute’s Breakthrough: Turning Tailings into High-Value Powders
Through decades of research, field trials, and the integration of previously held patents, Involute has developed advanced technologies including double-stage reduction, DRI-based processing, and specialized powder metallurgy routes.
From tailings that cost roughly ₹500–1,500/tonne, it is possible to produce High worth Sponge-iron powders with a market value of ₹75,000–90,000/tonne. These processes convert low-grade ores, ultra-fines, and dusts (below 50 microns) into:
- Sponge iron powders
- Magnetite powders
- Ferrous and non-ferrous alloy powders
This innovation has the potential to reduce India’s reliance on powder imports from China, Spain, and the US by up to 45%, directly strengthening India’s Atmanirbhar Bharat and Make in India ambitions.
A National Impact Across Core Industries
The high-value powders produced from tailings support critical sectors such as:
- Steel
- Automotive and EV manufacturing
- Aeronautics and aerospace
- Defence and strategic materials
- Advanced engineering and metallurgy
By integrating waste back into the production cycle, Involute brings a major boost to India’s manufacturing competitiveness while offering a sustainable, circular-economy model.
Environmental & Economic Transformation
Involute’s technology ecosystem not only converts waste to wealth but also:
- Reclaims vast land areas occupied by tailings
- Reduces pollution and ecological risks
- Supports vegetation, land restoration, and eco-rehabilitation
- Enables downstream MSMEs with cost-efficient raw materials
The solution represents a convergence of industrial innovation, environmental stewardship, and economic value creation.
A Strategic Call for Industry & Policy Collaboration
Head of Involute Metal Powders, Ms.Soumya Vilekar, shared, “Involute emphasizes that wider adoption of tailings-to-powder technologies—supported by policy incentives, reduced raw material taxes, and manufacturing subsidies—could reshape India’s industrial landscape. With coordinated support, India can emerge as one of the world’s largest producers of iron-based and alloy powders” .With over four decades of expertise in powder metallurgy and material sciences, Involute continues to drive innovation in the utilization of waste materials, advanced reduction processes, and industrial sustainability. The company remains committed to building technologies that align economic growth with environmental responsibility.
