With a composition of approximately 70 wt% water (with some unrecovered bitumen) and 30 wt% solids (&gt;90% less than 44 {mu}m in size), these clay suspensions consolidate very slowly. Clay aggregate or floc morphology has been shown to be a function of the water chemistry and can be manipulated to produce a tailings suspension that is easier to consolidate and dewater. Commercial oil sands processing has been going on in northeastern Alberta since 1967, and in that time approximately 250 million m of this difficult to dewater clay suspension has been produced. The reclamation options for this material (mature fine tailings) on a commercial scale are also outlined. 84 refs., 36 figs., 3 tabs.</style></abstract><custom2><style face="normal" font="default" size="100%">Alberta oil sands </style></custom2><custom3><style face="normal" font="default" size="100%">http://www.worldcat.org/oclc/4438070229</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
