The metal sequestration is, however, very challenging becomes WEEE contains several components and materials from which the wanted metals should be recovered in a selective, effective, economic, and environmentally friendly manner.<\/p>\n<p>Chemists from Helsinki and Jyv\u00e4skyl\u00e4 Universities collaborated to investigate a novel method for recovering gold, silver, and copper from WEEEs. The experimental work demonstrated the efficiency of the sequential dissolution approach, but it remained unclear how and why different metals are dissolved in a given solvent-oxidant mixtures. The researchers at the Department of Chemistry at the University of Jyv\u00e4skyl\u00e4 developed a theoretical model, which could explain the experimental results.<\/p>\n<p>The results showed that recycling and recovery of very complex and heterogeneous WEEEs can be understood, and even predicted, using rather traditional approaches of inorganic, physical, and computational chemistries.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.jyu.fi\/en\/news\/collaborative-insight-on-the-circular-economy-of-gold-silver-and-copper\">University of Jyv\u00e4skyl\u00e4<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/1-537\/\">Collaborative insight on the circular economy of gold, silver, and copper<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[838,1167,575,1122,10281],"class_list":["post-131207","post","type-post","status-publish","format-standard","hentry","category-news","tag-circular-economy","tag-copper","tag-environmental-news-en","tag-gold","tag-silver"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/131207","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=131207"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/131207\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=131207"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=131207"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=131207"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
