TAILINGS-POLYMER MIXING OPTIMIZATION BY CONTROLLING THE DISCHARGE ENVIRONMENT

A process for dewatering tailings is provided comprising providing a tailings feed having a solids content in the range of about 10 wt% to about 70 wt%; adding an effective amount of a polymeric flocculant to the tailings feed and, optionally, mixing the polymeric flocculant and tailings feed mixtur...

Beschreibung
Zusammenfassung:	A process for dewatering tailings is provided comprising providing a tailings feed having a solids content in the range of about 10 wt% to about 70 wt%; adding an effective amount of a polymeric flocculant to the tailings feed and, optionally, mixing the polymeric flocculant and tailings feed mixture in a mixer; transporting the tailings feed and polymeric flocculant mixture to a deposition area; and optimizing the overall mixing and therefore dewatering rate of the tailings feed and polymeric flocculant mixture by controlling the conditions used for discharging the mixture to a deposition area.
