  • Patent number: 4251034
    Abstract: Chrome plated plastic scrap is chopped into small pieces and then, while subjected to sub-zero temperatures, is centrifugally impacted thereby producing a mixture of particles of chrome and plastic. Most of the chrome particles are removed by subjecting the mixture to a magnetic field. The remaining, mostly plastic particles are classified to obtain usable, predominantly plastic particles within a predetermined size range, those particles exceeding this range being, if desired, recycled for subjection to said centrifugal impacting step. The usable particles are thus reclaimed for reuse, after repelletizing, in extrusion or molding techniques.
