#17 - Mohan Yellishetty: What to do with a hole in the ground - re-mining for critical minerals, rehabilitation and repurposing
Description
Mohan Yellishetty from Resources Engineering at Monash University, Australia sheds light on the importance of minerals extraction and how we can undertake this sustainably. From fascination with Australia-India relations around cricket to growing up in the countryside in India, we discuss the life cycle of mines and the potential of 're-mining', rehabilitation and repurposing after their closure as a way to combat climate change and support the global economy.
