POSSIBILITIES OF CHEMICAL TREATMENT OF RAW MATERIALS AND THE SUBSEQUENT ELECTROWINNING OF METAL IN MOLTEN CHLORIDES. REVIEW OF PREVIOUS RESULTS

摘要

The long term goal of our research is to develop a continuous process for the treatment of ores and industrial slags in molten salts and the subsequent electrowinning of metals. The fields of our research are described as follow: 1. The use of low temperature molten salt mixtures for light metal production. 2. The use of low temperature molten salt mixtures for the production of refractory metals by a continuous process involving chlorination of the ores and the subsequent electrolysis. This process may also be considered for the purpose of electroplating. 3. The treatment of lead and zinc concentrates from industrial slags by dissolution in a selected molten salt mixture with the subsequent recovery of metals by electrolysis. This process may also be used for metals containing wastes. 4. Study of the possibility of preparing semiconducting materials
