Abstract
To optimize recovery by the hot water process of hydrocarbons from bituminous sands, an alkaline process aid (e.g. NaOH) is commonly added to the conditioning step. In accordance with this invention, the quantity of process aid added is varied in response to the fines content of the incoming bituminous sands feed.
