Flotation in times of circular economy and energy transition

Summary: The invention of flotation about 140 years ago was one of the great achievements of modern processing technology. For many metallic/mineral raw materials, processing without a flotation stage would be unthinkable. This article presents the especially important topics in the field of basic research and technological development of flotation in times of the circular economy and energy transition.
