The venture, being developed in collaboration with the Bhabha Atomic Analysis Centre (BARC), seeks to recuperate uncommon earth components from fly ash generated at NLC’s Neyveli operations in Tamil Nadu. If profitable, it may open up a brand new home supply of strategic minerals at a time when India is looking for to cut back dependence on imports of crucial supplies required for clear power applied sciences, superior manufacturing, and healthcare purposes.
“The pilot venture is on the tendering stage, and we anticipate to award it throughout the subsequent two months,” NLC Chairman and Managing Director Prasanna Kumar Motupalli informed Enterprise Normal in an unique interview.
The venture is being arrange with help from BARC to reveal the superior extraction course of, with the presence of uncommon earth components already recognized.
“NLC has recognized the presence of uncommon earth components in fly ash generated from its lignite-based energy stations in Neyveli. The focus of uncommon earth components in Neyveli fly ash is substantial, and the venture has generated important curiosity amongst stakeholders,” Motupalli mentioned.
The corporate estimates an funding of round ₹600 crore for the pilot venture. Topic to profitable pilot outcomes, NLC expects the commercial-scale venture to contain investments of greater than ₹5,000 crore.
“The pilot facility is anticipated to be commissioned inside eight to 9 months of the award, with pilot-scale manufacturing focused inside about one yr,” Motupalli mentioned.
Among the many uncommon earth components recognized within the fly ash is lutetium, a high-value steel utilized in nuclear medication, focused most cancers therapies, medical imaging, and scientific analysis. The corporate has additionally recognized a number of different uncommon earth components that would probably be recovered economically, together with cerium, neodymium, lanthanum, samarium, gadolinium, praseodymium, and europium.
A number of of the uncommon earth components recognized by NLC have strategic industrial purposes and play essential roles in rising applied sciences. Neodymium and praseodymium are utilized in high-performance everlasting magnets deployed in electrical autos and wind generators, whereas europium is utilized in lighting and show applied sciences. Cerium and lanthanum are broadly utilized in catalysts, batteries, and optical purposes, whereas samarium and gadolinium discover use in aerospace, defence, electronics, and medical applied sciences.
India has stepped up efforts in recent times to safe home provides of crucial minerals and cut back its dependence on China for imports amid rising world competitors for assets important to the power transition. Whereas most initiatives have targeted on typical mining and abroad asset acquisitions, the NLC-BARC venture seeks to unlock worth from industrial waste streams.
Motupalli mentioned NLC generates roughly 5,000-6,000 tonnes of fly ash within the Neyveli space, which may function feedstock for the extraction course of. If the pilot demonstrates industrial viability, the venture may present a brand new avenue for recovering strategic minerals whereas concurrently addressing fly ash-utilisation challenges.
