Scientists develop technique to reduce cost, environmental impact of mining precious metal
Mining.com reports that researchers at the University of Notre Dame invented a new class of molecules whose shape and size enable them to capture and contain precious metal ions.
In astudypublished in theJournal of the American Chemical Society, the scientists explain buy phentermine online that the method they have developed converts gold-containing ore into chloroauric acid and extracts it using an industrial solvent. The container molecules are able to selectively separate the gold from the solvent without the use of water stripping.
