Abstract
A system for the recovery of titanium, titanium alloys, zirconium and zirconium alloys is disclosed. The system is fed with a mixture of chips including titanium chips, titanium alloy chips, zirconium chips and zirconium alloy chips, ferromagnetic chips and electrically conductive non-ferromagnetic chips. The system has at least one magnetic separator, a drying device and an Eddy current separator.
Claims7
A process for recovering titanium, titanium alloys, zirconium and zirconium alloys from a mixture of chips, the mixture of chips including titanium chips, titanium alloy chips, zirconium chips, zirconium alloy chips, ferromagnetic chips, electrically conductive non-ferromagnetic chips or mixtures thereof, the process comprising;
- drying the mixture of chips;
- demagnetizing the mixture of chips so as to eject ferromagnetic chips from the mixture of chips;
- decontaminating the dried mixture of chips after the step of demagnetizing by passing the dried mixture of chips in an Eddy current separator so as to eject electrically conductive non-ferromagnetic chips from the dried mixture of chips;
- and
- demagnetizing the decontaminated dried mixture of chips so as to eject ferromagnetic chips from the decontaminated dried mixture of chips.
