THE USE OF ISOBARIC-POLYTHERMAL SOLUBILITY DIAGRAM PROJECTION OF NA2CO3-NA2WO4 (NA2MOO4) – H2O SYSTEM FOR DEVELOPMENT OF SODA REGENERATION TECHNOLOGY FROM AUTOCLAVE SOLUTIONS
Abstract
It is shown that the introduction of this method of soda regeneration in production will significantly intensify the process of autoclave soda leaching of tungsten products, especially of poor and difficult to leach concentrates, by increasing the soda equivalent.
