Technology Of Tailings Treatment Process Flow

Tailings Reduction Technology Canada’s Oil Sands

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.

Filter press dewatering technology for tailings

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.
