"To go green, the world will need vast quantities of critical minerals such as
manganese, lithium, cobalt and rare earth elements. But to some
environmentalists, mining to save the planet is a hard pill to swallow if it
leads to damage to pristine areas.
The good news is that in many cases, the mining for these minerals has already
been done. After Australia’s major miners dig up iron ore, billions of tonnes
of earth and rock are left over. Hidden in these rock piles and tailing dams
are minerals vital to high tech industries of today and tomorrow.
In recent years, we have seen a welcome focus on remining – the extraction of
valuable minerals and metals from mining waste. While Australia has been slow
to adopt this approach, it holds real promise. We don’t necessarily have to
mine more. We can mine smarter."
