Abstract
In a method for reduction of a solid feedstock, such as a solid metal compound, in an electrolytic apparatus a portion of the feedstock is arranged in each of two or more electrolytic cells (50, 60, 70, 80). A molten salt is provided as an electrolyte in each cell. The molten salt is circulated from a molten salt reservoir (10) such that salt flows through each of the cells. Feedstock is reduced in each cell by applying a potential across electrodes in each cell, the potential being sufficient to cause reduction of the feedstock. The invention also provides an apparatus for implementing the method.
