Objective
THE AIM IS THE DEFINITION OF THE PROCESS TECHNOLOGY FOR ELECTROLYTIC RECOVERY, IN MOLTEN SALTS, OF TI RESIDUES.
A method had been developed in the laboratory and in a plant scale for successfully electrorefining titanium metal. Refining was accomplished in a molten salt electrolyte using off grade metal as the anode and collecting the purified metal at the cathode.
THE PROGRAMME WILL STUDY THE ELECTROLYTIC RECOVERY, IN MOLTEN SALTS, OF TITANIUM FROM SCRAPS AND MACHINING WASTES OF ALLOYS CONTAINING TI-AL-V, AND RESIDUALS OBTAINED FROM THE INGOT CONDITIONING PHASE.
THAT WILL BE OBTAINED BY ANODIC DISSOLUTION OF THE SCRAP AND CATHODIC DEPOSITION OF TI, BOTH CARRIED OUT IN MOLTEN SALTS ELECTROLYTIC BATH, MOSTLY CONTAINING SODIUM CHLORIDE.
EXPERIMENTATION WILL BE CARRIED OUT ON TECHNICAL SCALE CELLS, WHICH CAN TREAT ABOUT 50 KG/DAY OF SCRAP. THE WORK CONSISTS OF THE FOLLOWING PHASES:
A) PROJECT OF THE TESTING INSTALLATION TO USE FOR THE EXPERIMENTATION
B) CONSTRUCTION OF THE TESTING INSTALLATION TO USE FOR THE EXPERIMENTATION
C) EXPERIMENTATION:
- BOTH SCRAPS AND MACHINING WASTES (SUCH AS TURNING CHIPS ETC) OF THE MOST KNOWN TI-C-AL (6AL-4V) ALLOY WILL BE EXAMINED.
- MACHINING WASTES OBTAINED FROM THE CONDITIONING PROCESS OF THE FORGED SLABS, AND COMPOSED BY COMMERCIALLY PURE TI AND TI ALLOYS WILL BE TAKEN INTO CONSIDERATION.
- DESIGN OF THE CELLS GEOMETRY, OF THE MOSTLY SUITABLE ELECTRODES CONFIGURATION FOR SELECTIVE DEPOSITION;
- DEVELOPMENT OF PRELIMINARY TREATMENT METHODS ON THE SCRAP (CLEANING, DEGREASING ETC...);
- DETERMINATION OF THE OPERATIVE PARAMETERS WHICH ARE NECESSARY FOR TITANIUM SELECTIVE ELECTRODEPOSITION;
- DETERMINATION OF THE RELATION BETWEEN THE PROCESS OPERATIVE PARAMETERS AND THE DIFFERENT COMPOSITION OF THE SCRAP.
THE ANALYSIS OF THE RESULTS OBTAINED DURING THE EXPERIMENTAL STAGE WILL ALLOW THE DEFINITION OF THE SPECIFICATIONS FOR A PLANT SUITABLE TO THE ELECTROLYTIC RECOVERY OF TITANIUM, WHICH IS AN AMBITIOUS TASK.
