Graphene development company SPARC TECHNOLOGIES has demonstrated that its graphene product in solution can adsorb gold and silver from mine tailings dumps.Adsorption, not to be confused with absorption, is a process in which molecules are held loosely on the surface of an adsorbent.The company, which has licenced graphene-based technologies from the University of Adelaide,
has shown its product outperformed commercially available adsorbents,
opening up a large potential market treating minesite dumps.https://www.aumanufacturing.com.au/sparc-uses-graphene-to-extract-gold-from-tailingshttps://sparctechnologies.com.au/
A micro factory is a series of modules that can take a variety of different waste materials and transform them into a new product. Textiles for example can be combined with glass in the micro factory to be converted into hard green ceramics.The ideal location for these micro factories is where the waste is being collected so you can have communities able to access them and turn their own waste into a resource, a small-scale industry.https://www.abc.net.au/austory/the-tipping-point/13164736
