Abstract
La présente invention concerne un procédé de production électrolytique et de raffinage de métaux ayant un point de fusion au-dessus d'environ 1000 °C, en particulier du silicium, dans lequel on propose une première cellule électrolytique comportant une couche électrolytique fondue supérieure d'un premier électrolyte, une couche d'alliage fondu inférieure d'un alliage du métal à raffiner et au moins un métal plus noble que le métal à raffiner. La couche d'alliage inférieure est la cathode dans la première cellule et une anode est positionnée dans ladite couche supérieure. Une seconde cellule électrolytique est également dotée d'une couche de métal fondu supérieure du même métal que le métal à raffiner, ladite couche constituant une cathode, d'une couche d'alliage fondu inférieure, ladite couche inférieure constituant une anode, ledit alliage ayant une densité supérieure au métal à raffiner, et une couche électrolytique fondue intermédiaire ayant une densité comprise entre la densité des couches supérieure et inférieure fondues. Les deux électrolytes sont des électrolytes à base d'oxyde contenant un oxyde du métal à raffiner et l'électrolyte est à l'état fondu et a un point de fusion en dessous de la température d'utilisation du procédé. Une matière première comprenant un oxyde du métal à raffiner est ajoutée à la première cellule et un courant électrique continu traverse l'anode vers la cathode de telle sorte que le métal à raffiner est déplacé à partir de l'anode et déposé à l'état fondu sur la cathode. Les deux cellules peuvent fonctionner en deux étapes séparées, l'une pour produire un alliage et l'autre pour raffiner le métal à partir de l'alliage.
