TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The matrix including solids is crude (I) produced from an oilsand formation. The separation enhancing additive is a condensed nonylphenol-formaldehyde hexamer adducted with 50 wt.% ethylene oxide averaging about six hydroxyl terminated chains averaging six moles ethylene oxide each. The separation enhancing additive is added to (A) prior to addition of (B). The separation enhancing additive is dissolved in an additive solvent prior to its addition to (A). Preferred Components: The separation enhancing additive is alkoxylates of alkylphenol-formaldehyde condensates and/or alkoxylates of alkylene bisphenol diglycidyl ethers. The additive solvent is xylenes, naphthas, kerosenes, dry alcohols, ethers and/or esters. The separation enhancing additive is 20-2000 (preferably 50-800) parts of separation enhancing additive per million parts of diluted (I).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The separation enhancing additive is a polymeric surfactant. The polymeric surfactant has multiple lipophilic and hydrophilic moieties. The lipophilic moieties are lipophilic aromatic groups. The hydrophilic moieties are hydroxylated hydrophilic polyether groups. The polymeric surfactant has: an aromatic moiety content of 15-65 (preferably 40-60) wt.%; a hydroxylated hydrophilic polyether content of 35-85 (preferably 40-60)%. The polymeric surfactant (II) of formula -(Z)y-((A)(OE)xOH)-.A = an aromatic moiety;Z = a connecting moiety;(OE)xOH = a hydrophilic moiety;OE = a hydrophilic polyether;x = 3-30; andy = 2-20. EXAMPLE - Cylindrical pot was filled with one part bitumen from froth flotation of Albertan oilsand, a mixture of pentanes and hexanes, and separation enhancing (160 ppm). The separation enhancing was an ethyoxylated acid catalyzed nonylphenol formaldehyde condensate having ethyleneoxide (50%). The contents are heated and mechanically mixed. The tube was allowed to sit until the insoluble materials settles (asphaltic sludge) to the bottom. The asphaltic sludge was fluid. The reaction was further worked up to give bitumen.
