Abstract
An extraction method is presented which relies on supercritical carbon dioxide as extractant. The development of the method and its demonstr ation in a bench-scale facility are described by the example of residu es with high mineral oil and lead contents from machining optical glas ses, the so-called glass grinds. By the extraction method,the oil can be recovered from the grinds in such a quality that direct recycling a s grinding oil is possible.
