that's already being achieved, and the mineral used is halite. The WIPP (Waste Isolation Pilot Plant) website close to Carlsbad, NM is the place mid-point radioactive waste (from hospitals and different web content) is saved under Permian salt beds. Salt beds are frequently composed of halite (sodium chloride) and sylvite (potassium chloride), and the plasticity of the layers finally seals the waste. Neither quartz (which exists as sand) nor feldspar make logical selections to try this. There are no longer any deposits of feldspar to try this, and quartz sands do no longer enable for sealing like salts beds do.
