Process role
Coarse sand settles more readily while fine clay can remain fluid much longer.
How the system fits together
Water recovered from tailings is reused in the extraction process.
Environmental and reclamation context
The remaining fluid tailings and process-affected water are among the sector’s largest long-term reclamation liabilities.
What to keep in mind
Tailings treatment has improved management, but accumulated volumes and long timelines remain real challenges.
