Mineral Sponges May Help Absorb Residual Uranium from Contaminated Sites
A group of researchers from Pacific Northwest, Lawrence Berkeley and Sandia national laboratories have discovered a mineral that can absorb uranium from ground water. The researchers discovered the mineral, which is known as calcium apatite, at a former uranium mill in Colorado. The sponge-like mineral reduced the levels of uranium in groundwater significantly. The project’s lead Mark Rigali, a geochemist from Sandia, stated that apatite technology was also found to decrease the concentration of molybdenum, vanadium and uranium in the groundwater at Colorado’s Rifle mine site. Additionally, it ensures that the uranium amounts remain below the target concentration set by…
