    Abstract:

Applications: Promotes urban mining through recovery of rare earths oxides (Nd, Pr, Dy) from spent permanent magnets, thereby reduces environmental impacts and carbon foot-prints caused during primary production. The recovered materials find applications in manufacture of IT- products, photonics, solid state lighting and fibre optic communications, etc.
Advantages: Recovery of rare earths elements like Neodymium, Dysprosium and Praseodymium from spent permanent magnets using a simple and commercially viable hydrometallurgical route.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
