2. 1. Mobilization of metals from mining wastes and the resuspension of contaminated sediments

   Author : Lan Thuy Nguyen; Bo Svensson; Gunnar Jacks; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acid Rock Drainage; hydropower plant; metal contamination; mining wastes; storm-wind; resuspension; sediment; Environmental chemistry; Miljökemi;

   Abstract : In some environmental situations, environmental effects caused by elevated metals resulting from past mining and smelting activities can be observed in nearby receiving water bodies several decades after mine and smelter closure. There is a growing need for managing the hazardous solid wastes such as mining wastes as well as for assessing water quality and for sustainable management of sediment quality. READ MORE

4. 2. Landfill mining approach for resource recovery from glass dumps into the circular economy

   Author : Richard Mutafela; William Hogland; Lennart Mårtensson; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resource recovery; landfill mining; hazardous waste; hydrometallurgical extraction; geophysical mapping; circular economy; Återvinning av resurser; gruvdrift; farligt avfall; hydrometallurgisk utvinning; geofysisk kartläggning; cirkulär ekonomi; Miljövetenskap; Environmental Science;

   Abstract : Landfills and open dumps have been the most cost-effective waste disposal option, resulting in over 500,000 landfills and dumps in the EU alone. They pose significant environmental and health threats due to emission of toxic gases and release of persistent contaminants to soil and groundwater, triggering a considerable global economic impact annually.

5. 3. Reprocessing historical tailings for possible remediation and recovery of critical metals and minerals : The Yxsjöberg case

   Author : Jane Mwaba Mulenshi; Jan Rosenkranz; Saeed Chehreh Chelgani; Urs Peuker; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining waste; Historical tailings; Conceptual framework; Critical raw materials; Tungsten; Scheelite; Characterization; Mineral liberation analysis; Beneficiation; Reprocessing; Mineral Processing; Mineralteknik; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ;

   Abstract : With increasing consumption of primary mineral resources, the generation of mining wastes has also increased thus requiring the mining industry to address the growing environmental concerns. Waste rock and tailings are potential secondary sources of critical raw materials currently in short supply in the European Union, but also a source for environmental issues like acid mine drainage.

6. 4. Landfills and glass dumpsites as future bank accounts of resources : waste characterization and trace elements extraction

   Author : Yahya Jani; William Hogland; Monica Odlare; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landfill mining; metals extraction; glass dumpsites; hazardous waste; chemical extraction; reduction-melting; Miljövetenskap; Environmental Science;

   Abstract : Environmental pollution and health threats as well as scarcity of raw materials, water, food and energy are among the main challenges our world are now facing. Simultaneously, landfills and open dumpsites still are the dominant global waste disposal option even with their long term environmental impacts in case of greenhouse gases and contaminated leachates.

7. 5. Application of Wastes from Pulp and Paper Industries for Steelmaking Processes

   Author : Tova Jarnerud; Andrey Karasev; Pär Jönsson; Carl-Erik Grip; KTH; []
   Keywords : Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : Over the past several years, considerable efforts have been made to develop a more circular economy. The ambition to reuse, remanu­facture and recycle materials is of great significance for the establish­ment of a sustainable society. READ MORE
