摘要： A process for treating and dewatering tailings comprising fine clay minerals, fine rock-forming minerals and water is provided, comprising treating the tailings with a sufficient amount of a collector to modify the surface properties of both the fine clays and rock-forming minerals; subjecting the treated tailings to froth flotation to form a fine clays and rock-forming minerals froth layer; and recovering the froth layer and subjecting it to dewatering.

摘要： A method for controlling the solids distribution in a bitumen froth produced when processing an oil sands ore having a d50 of about 250 μm or greater and a d90 of about 450 μm or greater is provided comprising adding a high-fines material having a d50 of about 50 μm 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.

摘要： A process for extracting bitumen from mined oil sand is provided, comprising: preparing an oil sand slurry comprising oil sand and water; conditioning the oil sand slurry by pumping the oil sand slurry through a hydrotransport pipeline under shear conditions that reduce the formation of water-in-bitumen emulsions in the conditioned oil sand slurry and increase the size of bitumen-air aggregates; and subjecting the conditioned oil sand slurry to gravity separation to produce a bitumen froth having enhanced bitumen recovery and reduced water-in-bitumen emulsions, a middlings layer and sand tailings.

摘要： 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.

摘要： A method for recovering hydrocarbon diluent from froth treatment tailings comprising bitumen, solids, hydrocarbon diluent and water is provided, comprising: introducing the froth treatment tailings into a vessel chamber and allowing the coarse solids to settle to the bottom of the vessel and form a solids layer having a portion of hydrocarbon diluent and a portion of water trapped therein; and heating the water in the solids layer to generate steam bubbles in-situ and strip the hydrocarbon diluent associated with the coarse solids to produce stripped tailings.

摘要： A method of quantifying at least one property of interest of an oil sands ore sample is provided using a laser-induced breakdown spectroscopy (LIBS) method. The property of interest may include bitumen content, water content, particle size information, cation exchange capacity, methylene blue index, mineralogical content (e.g., quartz, total clay, and clay components), amorphous material content, total ash content, and connate water parameter (e.g., conductivity, chloride content, or alkalinity).
