    #GoldExtraction from #EWaste gets 10 times more efficient with new sponge material

    Researchers developed a nanoscale cross-dimensional composite material via self-assembly of two-dimensional graphene oxide and one-dimensional chitosan macromolecules.

    By Prabhat Ranjan Mishra, Oct 27, 2024

    "Researchers have developed a new type of material that’s 10 times more efficient at extracting gold from e-waste than previous adsorbents. Developed by chemists and materials scientists at the National University of Singapore, the material is a type of sponge made of #GrapheneOxide and #chitosan [shrimp shells].

    "The material can reportedly transform the way gold is extracted from electronic wastes, which has been described so far as a dirty business with low yields and results in toxic #pollutants.

    "The cheaper, cleaner and efficient method was tested by researchers using real e-waste provided by a recycling company."

    [...]

    "While the present work focused on gold, the team say the technique could be adapted to recover other valuable metals such as #silver, #platinum or #palladium from #ElectronicWaste or even #mining residues. And that is not all: as well as e-waste, the technology might be applied to a wider range of environmental cleaning efforts, such as filtering out #HeavyMetals from #PollutedWater sources or industrial effluents, reported Physics World."

    GENEVA -- "#Indigenous from Brazil urged the United Nations to join them and demand Brazil halt illegal gold mining, and its #mercury #contamination, now destroying the ancestral homelands of #Kayapó, #Yanomami and #Munduruku Peoples, during the U.N. Expert Mechanism on the Rights of Indigenous Peoples.

    "Doto Takak Ire, Mebêngôkre, said, 'The Kayapó are still warriors and we will always be defenders of the forests.'

    "'We do not want any kind of #exploitation of #NaturalResources in our territories. We want the #Amazon protected, so that our children and all the children of the world can grow up healthy.'"
