null New book: Principles of Metal Refining and Recycling

Anne Kvithyld. PhotoCongratulations to SFI research area leader Anne Kvithyld with the publication of the book Principles of Metal Refining and Recycling. The book provides a self-contained introduction to the field of purification and recycling of metals. 

The scientific principles in the treatment of the various metals are the same. The importance of using a clean and properly alloyed metal is described in detail. The text covers thermodynamics, physical and transport properties, mixing, mass transfer and numerical models. It describes methods for removal of dissolved impurity elements, particles, and inclusions. It considers important aspects of the solidification process, remelting and adding of alloys. Recycling, future challenges and specific processes for each metal are discussed in detail. 

Authors are Thorvald Abel Engh (NTNU), Geoffrey Sigworth (GKS engineering) and Anne Kvithyld (SINTEF), and the work has been partly funded by SFI Metal Production. The book is a greatly extended update of the 1992 book Principles of Metal Refining by T. A. Engh. It includes in particular the subjects of metal recycling, ferrous and non-ferrous metal refining, and metalloids like silicon.
