GEA decanters improve management of tailings

Traditionally, mine tailings, in the form of a slurry containing fine mineral particles, have been contained in large, man-made lakes where the solids are allowed to settle out and then the cleaned water skimmed off the surface. However, this process is less than ideal. Settling takes a long time which means tailings ponds can become quite large.
