ABSTRACT:
The present invention is a process for reclaiming and recycling oil/water mixtures. These mixtures are preferably hot or cold rolling oils for aluminum manufacturing operations. When used, the rolling oils contain organometallic particles and have less constituents than the unused oils. The present process enables the valuable portion of the oil to be reused by passing through an acid wash and a reconstitution process.
