Pyrochemical processing
Pyrochemical processing consists of putting the elements to be partitioned in solution in a high-temperature bath of molten salt. The elements of interest are selectively recovered using various chemical engineering techniques: extraction by molten metals, electrodeposition and precipitation. In this liquid medium, the effects of the radiation are limited. It is a compact system but there is as yet no knowledge of how well it will perform. The molten salt is highly corrosive and it will difficult to implement.
