Ore Conservation is a Major Benefit When Scrap Metal Gets Recycled

Mining ore can also lead to acid rock drainage. Acid gets created when water and oxygen interact with sulphur-bearing minerals and chemicals within the rocks. Sulphuric acid can result from mining activities, since the beneficiation process requires dissolving the minerals surrounding the ore. That releases chemicals in the rock.
