Abstract

Oils or petroleum hydrocarbons are separated from solid or solid/liquid mixtures thereof with soil, sand or oil processing residues, by treating these oil-containing mixtures with an aqueous solution or dispersion of a crude extract of microbially produced glycolipids and separating the oil-containing phase from the aqueous phase.
