| abstract |
The invention relates to a feedstock for reduction in an electrolytic cell, for example a non-metallic feedstock that can be reduced to metal on a commercial scale. The feedstock comprises a plurality of three-dimensional elements which are shaped such that a volume of the feedstock has between 35% and 90% free space (not including any microscopic porosity of the elements). The elements are also shaped as randomly-packable elements to minimise any settling, ordering or alignment of the feedstock, which would otherwise hinder or prevent fluid flow and/or current flow through the feedstock. |
