The method suffers from the disadvantage that the dam wall is built on the top of previously deposited unconsolidated slimes retained behind the wall. There is a limiting height to which this type of dam can be built before failure occurs and the tailings flow out and, because of this, the upstream method of construction is now less commonly used.
Read MoreInmarsat, in collaboration with Knight Piésold UK, have won the Mining Magazine 2019 Editor's Award for their innovative Tailings Dam Monitoring Solution. The technology allows mining companies to remotely monitor tailings dams in real time, in order to support independent analysis from auditors to guide critical decision making.
Read MoreTailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.
