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 flotation.
In the mineral processing area, all employed flotation devices do not generate these microbubbles but coarser bubbles, usually between 600 and 2500 μm. according to most researchers, the lack of mid-sized bubbles in the cells is the main reason why the capture of the very fine particles is inefficient leading to considerable losses flotation.
