How does the environmental impact of mining for clean energy …
Odell believes that the way forward for clean energy mining is through three main changes. The first is to reduce consumption so we need fewer materials in the first place, such as by investing in more public transportation and walkable cities, which would reduce the need for mineral-intensive EVs. The second is to advance the circular economy ...

Microwave processing of ore
This stage liberates minerals from one another before separation and is one of the most energy-intensive processes in the mining industry. Comminution consumes 50% to 70% of the energy used in mineral processing and can be as little as 1% efficient as significant energy is lost to heat, vibration, and noise.
