Kinetic Investigation of Silver Recycling by Leaching from Mechanical Pre-Treated Oxygen-Depolarized Cathodes Containing PTFE and Nickel

Autor: Jil Schosseler, Anna Trentmann, Bernd Friedrich, Klaus Hahn, Hermann Wotruba

Publikováno v: Metals, Vol 9, Iss 2, p 187 (2019)

This paper focuses on the recycling of silver from spent oxygen-depolarized cathodes through an innovative combination of pre-treatment methods and leaching. A silver- and polytetrafluorethylene (PTFE)-rich fraction was produced by cryogenic milling,

Metallurgical Effects of Introducing Powdered WEEE to a Molten Slag Bath

Autor: Frederic Brinkmann, Bernd Friedrich, Anna Trentmann, Nikolaus Borowski, Matthias Stürtz

Publikováno v: Journal of Sustainable Metallurgy. 4:233-250

Powders and dusts from e-waste recycling processes are a valuable source for different metals like copper or precious metals such as silver and gold. Hence, the recycling of this fine fraction is of great interest. In addition to these precious metal

Processing of Grinding Slurries Arising from NdFeB Magnet Production

Autor: Thomas Pretz, Karoline Raulf, Bernd Friedrich, Anna Trentmann, Stephanie Kruse

Publikováno v: Chemie Ingenieur Technik. 87:1589-1598

Neodymium-iron-boron (NdFeB) grinding slurries are the residual output of grinding as shaping process step in the production process of sintered NdFeB magnets. The treatment of the grinding slurries with the aim of recovering rare earth elements may
