Subarctic Weathering of Mineral Wastes Provides a Sink for Atmospheric CO 2

The mineral waste from some mines has the capacity to trap and store CO2 within secondary carbonate minerals via the process of silicate weathering. Nesquehonite [MgCO3•3H2O] forms by weathering of Mg-silicate minerals in kimberlitic mine tailings at th
