Mining extraction and processing generate large volumes of metal-rich waste tailings. This tailing is considered to be a principal cause of soil contamination in mining areas. Once these toxic metals are introduced into soils with surface water, they can be transported deep into the soil and into groundwater, threatening environmental health.
