| Abstract Scope |
Albeit electrodialysis is a membrane process originally developed for sea water desalination, it is possibly even more suited for separation in various hydrometallurgical processes. Several examples of such process have been demonstrated or demonstrated in a relevant environment. Particularly this context is when it comes to separating cations with different valences or likewise for anions of different valences. This has been done successfully by using membranes that are modified on the surface as to block ions of higher valences. Moreover, when having compositions with components of large differences in molarity, it has been demonstrated that utilisation of the boundary layer transport properties can be used for cationic species separation or likewise for anionic species separation. Given these examples the possibility for electrodialysis in hydrometallurgical processes is vast. The presentation will highlight some of these possibilities. |
