MANAGING ORE BLENDING FOR FROTH SOLIDS CONTROL

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 ab...

Zusammenfassung:	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. Il est décrit une méthode de contrôle de la distribution de solides dans une mousse de bitume produite lors du traitement dun minerai de sables bitumineux ayant un d50 denviron 250 µm ou plus, ainsi quun d90 denviron 450 µm ou plus, comprenant lajout dun matériau riche en fraction fine ayant un d50 denviron 50 µm ou moins et un contenu de fraction fine denviron 40 % des solides ou plus au minerai de sables bitumineux pour former un mélange de minerais; et le traitement du mélange de minerais dans un procédé dextraction de bitume à base deau afin de produire la mousse de bitume.
