Abstract
A process for treating waste rolling oil in the form of an oil and water emulsion. The oil and water emulsion is used during the cold rolling of steel to reduce the thickness thereof and is treated by breaking the emulsion with waste pickling acid solution and thereafter converting iron ions present in the waste pickling acid solution to magnetite particles which absorb the oil. The magnetite particles and the oil absorbed thereby are separated from the solution leaving a clarified solution.
