Spearheaded by Dr. Resmi Sebastian, an assistant professor at the institute’s Civil Engineering Department, the team stumbled upon tantalum during unrelated experiments, focusing on the dynamic properties of soil and rocks concerning seismic activities.
A team of researchers found the rare metal in the Sutlej river sand in Punjab region. This unforeseen discovery has raised questions about the economic viability of mining such rare metals, prompting further exploration.
Tantalum holds immense value in the realm of electronics and semiconductors. Punjab Mining and Geology Department Director Abhijeet Kaplish emphasized the significance of this finding, not just for Punjab but for India as a whole.
The results of the experiments, conducted in July 2021 and published in January of the following year, have been compiled in a research paper. IIT-Ropar has submitted a proposal to the Punjab government focusing on socio-environmental sustainability in river sand mining.
While the exact source of tantalum in the Sutlej region of Punjab remains unclear, Dr. Sebastian theorizes a connection to tectonic plate movements in the Himalayan region. The seismic activities might be causing the release of rare minerals, including tantalum, into the river.
Dr. Reet Kamal Tiwari, leading the research proposal team, suggests that without further investigations, speculating on the source is premature. They are considering factors such as the absence of industries upstream in Ropar and even the possibility of the tantalum originating from China, given that 80% of the Sutlej’s catchment area is in Tibet.
This unexpected discovery opens up new avenues for research, as scientists contemplate the potential economic and industrial implications of harnessing rare metals from river basins. Tantalum, classified as one of the 12 critical and strategic minerals by the Union Ministry of Mines (2020-21), is a durable and corrosion-resistant transition metal.
This tantalizing revelation not only adds a new dimension to geological studies but also underscores the need for extensive research to unravel the mysteries beneath the Earth’s surface, promising potential advancements in technology and industry.
