A process suitable for operation at a mine site for recovering a hydrocarbon from a hydrocarbon bearing sand comprising the steps of mixing a chemical additive with a chemical composition and with a hydrocarbon bearing sand containing hydrocarbon and residual solids including clay, at a temperature to form a slurry. The chemical composition comprises an aqueous phase and a minor amount of a chemical agent selected from the group consisting of at least one ethoxylated alkylphenol compound, at least one ethoxylated dialkylphenol compound, MIBC, SC-177, Petronate HL, Calcium Lignosulfonate, NaOH and mixtures thereof. The slurry is conditioned and aerated to produce essentially sludge-free tailings and a mixture of hydrocarbon, aqueous phase and residual solids including clay. The process further comprises the step of separating in a short-residence time apparatus the mixture of the hydrocarbon, the aqueous phase and the residual solids including clay from the essentially sludge-free tailings.
