Description:
The report gives results of a preliminary assessment of the technical feasibility and environmental acceptability of a fluidized-bed combustion (FBC) process for the disposal of spent potlining waste from the aluminum reduction process. Technical efforts included: (1) differential thermal analyses (DTAs) to establish the operating temperature range to prevent agglomeration in a FBC process, and (2) fixed-bed combustion experiments to determine cyanide destruction and gaseous emissions expected from a FBC process. The gaseous emissions, however, can be adequately controlled and should not pose an insurmountable technical barrier in the FBC process.
