Kevin Galvin is distinguished for his outstanding contributions to the field of mineral processing, particularly to the selective separation of valuable particles. He has made seminal contributions to the behaviour of fine particles in laminar shear flows, which has led to the invention of the Reflux Classifier, an innovative separator for recovering and concentrating high value minerals such as iron ore, chromite, coal, manganese and lithium. Since 2010, Reflux Classifiers have been installed around the world, processing raw materials and delivering significant economic impact, especially through the recovery of valuable minerals from waste materials.
