ABSTRACT:
The invention relates to a process for separating extractable organic material from a composition comprising organic material intermixed with solids and water. The composition is contacted with a solvent and a dehydrating agent. The dehydrating agent removes water, improves the solvent extraction, and aids in later separation of the solids from the solvent. The process additionally provides a means for removing cyanide compounds from the composition and fixating the metals against leaching.
