Separation of Aluminum from More Noble Elements in an Electrolysis Cell with Side-by-Side Geometry
Dissolution and Online Monitoring of Nd and Pr Oxides in NdF3-PrF3-LiF Electrolytes
Concentrations of dissolved rare earth metal oxides, Nd2O3, and Pr2O3 or their mixtures in different fluoride electrolytes composed of NdF3, PrF3, and LiF at ca. 1040 °C were monitored using a graphite probe inserted into the electrolyte during the dissolution process. Fast voltage sweeps of 100 V/s...

Pre-heating of alumina. Weight of rafts at different temperatures
It has been suggested that the alumina added to aluminium electrolysis cells should be pre-heated to obtain more rapid dissolution and thereby smoother operation. To investigate the effect of pre-heating, the formation of alumina "rafts" upon feeding a batch of alumina to the surface of molten...
