This reduces the time it takes to reclaim mature fine tailings and allows for the reduction of operating tailings ponds. Shell Canada is also using a technology, called Atmospheric Fines Drying (AFD), to speed the treatment of tailings and create a dry material that will allow for faster reclamation.

Disposal of tailings after recovery of useful iron minerals. In the on-site tailings production system, a tailings iron recovery and re-grinding system is added to recover the iron lost from the main process, and the tailings iron grade is reduced from 27% to less than 15%. This low value-added tailings can have three typical uses.

A key feature of Kearl’s tailings management is the use of thickener technology that intercepts the tailings produced by the extraction process and processes them into a paste prior to being placed in a deposit. These thickened tailings are placed in thin layers and allowed to dry into a solid state.
Get PriceThese filtered tailings are normally transported by conveyor or truck, deposited, spread and compacted to form an unsaturated tailings deposit (Davies and Rice 2001). This type of tailings storage produces a stable deposit usually requiring no retention bunding and is referred to as ‘dry stack’.
