PROCESSING OIL SANDS TAILINGS USING A BINDER AND AN ABSORBENT

A first binder is added to oil sands tailings to bind solid particles together, and then water is separated from the oil sands tailings. Thereafter, an absorbent is added to the oil sands tailings to absorb water and increase shear strength. The oil sands tailings are then deposited at a deposition...

Zusammenfassung:	A first binder is added to oil sands tailings to bind solid particles together, and then water is separated from the oil sands tailings. Thereafter, an absorbent is added to the oil sands tailings to absorb water and increase shear strength. The oil sands tailings are then deposited at a deposition area. The absorbent may be added after deposition.
