ABSTRACT:
The present invention provides a composition and method for separating bitumen from oil sands deposits. The invention includes a chemical composition having organic chemicals that can be used to stimulate the separation of one or more constituent components from oil sands. The chemical composition can be used for bitumen recovery from oil sands deposits and similar applications. The invention also includes a process for recovering bitumen and similar hydrocarbon oils from oil sands using the chemical composition. The chemical composition includes a peroxide and one or more additive compounds blended in an aqueous carrier solution. The additive compound is preferably a nitrogen-containing compound, an alcohol compound, or a combination of both. The aqueous carrier solution is of sufficient volume operable to disperse at least one of the peroxide and the additive compound in the aqueous carrier solution.
