  2. #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."

  4. 💧 Exploring how contaminated mine waters behave in a carbonate aquifer — through the lens of metasomatic zoning and thermodynamic #geochemical modeling.

    Using #PHREEQC simulations, data analysis in #RStats, and geospatial visualization in #QGIS, I’m studying how mine drainage transforms groundwater systems and mineral equilibria over time.

    📘 The draft version (v0.75) of my monograph on this topic has already been downloaded 550+ times on #Zenodo — showing how relevant this issue has become for both science and environmental policy.

    It’s independent research that links theory, modeling, and practical hydrogeochemical assessment — focused on the long-term impact of mine waters in the Kryvyi Rih region.

  5. 'It's a sick river. There are dangerous contaminants.'

    "The Belubula River is an endangered ecological community.

    "Foam containing high levels of the forever chemical PFOS have appeared on a river in central-west NSW for a second year.These concentrations just in the river are bad."

    'Future studies should include the assessment of likely real exposures: platypus, livestock or humans, together with PFAS fingerprinting," Professor Naidu said."

  13. At What Cost ?

    Mines #Tailingsdams have a sinister beauty – the colours are extraordinary. They contain #toxicwaste materials, such as #toxicchemicals and #heavymetals, which harm birdlife and ground water.

    It’s estimated that there are about 18,000 tailings dams around the world.

  14. #PrayerHorseRide's Third Annual March Ride Begins March 17, in Schurz, Nevada

    Reconnecting and Revitalizing #Traditional Ways of Life Threatened by Destructive #Mining Resource Extractions Supporting "#GreenEnergy"

    By Prayer Horse Ride, via #CensoredNews

    SCHURZ, Nevada -- "Prayer Horse Ride "#NanesootuhinaPookooGoobakatudu," is getting ready to begin our annual ride March 17th-26th, from Schurz, #Nevada through Yerington, Fallon, Wadsworth and Nixon, through Lovelock, then Orovada, and ending in #PeeheeMuhuh (#ThackerPass in the McDermitt Caldera), in the traditional, ancestral, and unceded lands of the #Paiute, #Shoshone, and #Bannock.
    The Riders, walkers, and runners carry the prayer with each community. They'll move forward to raise awareness regarding lithium mining in Peehee Mu'huh and the McDermitt Caldera; AND also raise awareness to #CopperMining in the #PineNutHills, a holy place known to the #Nuwu; in honor and remembrance of the Missing and Murdered Indigenous Women / People (#MMIW/P) in Nevada; and to revitalize and restore cultural identity, languages, creativity, and supportive lifeways in our indigenous communities.

    "Northern Nevada is the home of the #NorthernPaiute, #WesternShoshone, #Washoe, and #Bannock people. We, as descendants of them, will continue to give voices to the voiceless on #MotherEarth. To all of our relations.

    "'We do this prayer ride to reconnect and revitalize our way of life,' says Josh Dini, Sr, a member of Walker River Paiute Tribe, #WaterProtector and #PrayerHorseRider, and a member of #AmericanIndianMovement Northern Nevada (#AIMNNV).

    "Indigenous communities in the Great Basin and McDermitt Caldera are experiencing fast-tracked #mining and industrial development to support 'green energy,' and are threatened by #ecologically and #sociologically destructive resource extraction processes, most notably, #lithium and #copper mining, in areas in proximity to or within #communities, #reservations and #LandTrusts, and #SacredSites.

    "#HeavyMetals extraction #poisons lands, air, and water. Sacred sites for ceremony, where ancestors are buried, where medicines grow, and where lifecycles are anchored, are destroyed.

    "'Copper mining in our Pine Nut Hills takes away our knowledge and our identity of who we are,' says Dini, who explained the mining threatens an important Paiute medicine food, as well as numerous traditional campsites and sacred places that have been used for innumerable generations.

    "'We ride in honor of the people on the land before extraction industries, past - present - and future. Here in Nevada we have places important to the indigenous culture that are considered America's sacrifice zones in search of 'green energy.'

    "'We are Paiute and Shoshone allied with many of the federally recognized tribes in Nevada. We lead this prayer for Mother Earth,' says Gary McKinney, a Duck Valley Shoshone Paiute, water protector and Prayer Horse Rider, People of Red Mountain spokesperson, AIMNNV council member, and SIRGE Coalition Steering Committee member.

    Prayer Horse Ride will visit #Indigenous northern Nevada communities affected by these issues including #WalkerRiver Paiute Tribe, #Yerington Paiute Tribe, #Fallon Paiute Shoshone Tribe, #Lovelock Paiute Tribe, and #PyramidLake Paiute Tribe. As Riders reach each community, they may share meals, engage in ceremony, share stories and songs, and teach and learn traditional arts, bringing the communities together to celebrate and remember the traditional ways.

    "McKinney says, 'We ride to honor the land and the people - of the past, present, and the future. #LifeOverLithium."

    "About Prayer Horse Ride: Established in 2022 to honor the late #MyronDewey, Water Protector, Paiute Shoshone journalist and drone pilot, and to continue prayers for cultural sites like Peehee Mu’huh (Thacker Pass), we are an indigenous led prayer group and community service organization that advocates for our indigenous communities, to protect what we have left and to raise your awareness to what our communities face, and most importantly, in gathering tribes back together to stand in unity, not by separation.

    "'We'll continue this ride in the Vision of our Ancestors, for Healing, Strength and Awareness, in Prayer and Unity.'

  16. @ClimateNewsNow thank you for the reference to this comprehensive reporting. War is a toxic and environmentally destructive practice. Afghanistan has absorbed the damage of lethal machinery, lubricants, ordnance as well as the waste of hundreds of thousands of foreign fighters for 40 years: this is the first report I’ve seen of effects on people there. #burnpits #benzene #heavymetals #KBR #Bagram #kidneydisease #lungcancer #skinrashes
