Critical minerals are important for the growth of clean energy technologies, electric vehicles and battery manufacturing.
The demand for these minerals is increasing as the world transitions to clean energy. Critical minerals are also used in defence, such as in the production of aircraft, missiles, tanks, and corvettes, according to the report.
The country, it said, is steadily gearing its critical mineral resource security. However, challenges, such as low exploration levels, long gestation periods for mine operations, and bottlenecks in processing, highlight the need to look for alternative sources of critical minerals, with mine processing waste offering a promising solution.
Key mineral wastes in India, such as fly ash, red mud, mine overburden, mine tailings and metal slag, hold significant potential for the recovery of critical minerals such as nickel, cobalt, copper, gallium, and titanium.
