India is expanding deep sea mining with Varaha-3, harvesting significant polymetallic nodules

The National Institute of Ocean Technology (NIOT) has commenced significant research trials in the Andaman Sea using the specialized Varaha-3 seabed mining machine. These tests, which were conducted at a depth of 1,193 meters, are part of a broader Indian initiative to responsibly explore and use ocean resources. The Indian Geological Survey has previously carried out research in test locations, identifying them as potential places of valuable mineral resources, in particular polymetallic nodules.

Successful nodule collection

During the tests, Varaha-3 successfully collected polymetallic nodules ranging in size from 60 to 120 mm. These nodules contain essential metals such as nickel, cobalt and copper, which are essential to various industries, especially those focusing on renewable energy and electric vehicle production. The successful collection represents a significant advance in India’s deep mining capabilities.

Sustainable practices and future prospects

The Varaha-3 project emphasizes efficiency and minimizing environmental impact, which is in line with India’s commitment to sustainable management of ocean resources. Under the Deep Ocean Mission, the Government of India has made significant investments in the development of advanced deep sea exploration technology. This includes an integrated mining system that aims to increase the efficiency of nodule extraction and transportation.

Final remarks

These exploration trials not only showcase Varaha-3’s technical prowess, but also pave the way for potential future commercial mining operations. Through continuous research and innovation, India is leading the way in sustainable seabed extraction, contributing to the global demand for critical minerals essential for clean energy technologies.
