LKAB’s iron refining process in Vitåfors, Malmberget, is a source of great amounts of waste-rock. Most of the waste rock is, after separation from the ore, deposited dry in special storeges. But the finer fractions of waste rock, tailings, must be separated from the process water by sedimentation in a system of ponds, with several sub basins.
