As governments around the world look for ways to reduce carbon output and environmental impact, experts and individuals from in and out of mining are pushing the industry to take a serious look at how it can reduce its footprint.
One of the proposed ways is lower-impact mining techniques. Companies can reduce surface disturbance at mining sites, lower soil erosion and move less material.
Another way is reusing mining waste – tailings, rocks and wastewater. Companies can use waste rocks in simple on-site construction, like backfilling voids and reconstructing mined terrain in a way that prevents soil erosion. When adequately treated, mine water can be reused for agriculture, as coolant, in on-site dust suppression and for drinking water.
