A method for controlling the solids distribution in a bitumen froth produced when processing an oil sands ore having a dof about 250 &#x3bc;m or greater and a dof about 450 &#x3bc;m or greater is provided comprising adding a high-fines material having a dof about 50 &#x3bc;m or less and a fines content of about 40% of the solids or greater to the oil sands ore to form an ore blend; and processing the ore blend in a water-based bitumen extraction process to produce the bitumen froth.

Managing ore blending for froth solids control

A method is provided for controlling bitumen recovery from an oil sands ore body in a bitumen extraction process by establishing and using a predictive ore processability model that accounts for multiple ore characteristics in planning ore deliveries from different locations of the ore body to produce a blended ore feedstock.

A process for operating multiple oil sand mine sites for extracting bitumen from oil sand is disclosed, comprising preparing a first conditioned oil sand slurry at a first location using a first oil sand slurry preparation and slurry conditioning process; preparing a second conditioned oil sand slurry at a second location using a second oil sand slurry preparation and slurry conditioning process; combining the first conditioned oil sand slurry and the second conditioned oil sand slurry in at least one slurry distributor to produce a combined oil sand slurry; and distributing the combined oil sand slurry to at least one separation vessel to produce bitumen froth.

Bitumen production from single or multiple oil sand mines

A process is provided for treating an aqueous oil sand slurry containing bitumen droplets and air bubbles prior to separation in a separator, comprising separating the aqueous oil sand slurry into at least two individual slurry streams and allowing the at least two slurry streams to collide with one another such that the bitumen droplets and air bubbles in each slurry stream make contact with one another to increase both collision frequency and efficiency, and providing sufficient residence time to allow the bitumen droplet to coalesce, grow, and aerate to produce a treated oil sand slurry with larger and lighter bitumen droplets to improve bitumen flotation and recovery.
