TREATMENT OF BAUXITE RESIDUE AND SPENT POT LINING |
摘要 |
Methods of treating spent pot lining (SPL) and bauxite residue are disclosed. The treatment processes are capable of producing a ferrosilicon alloy, an off-gas, and/or a byproduct material resulting in the safe disposal of SPL and bauxite residue. The treatment processes may be continuously carried out in an electric arc furnace at a temperature in the range of from about 1500° C. to about 2200° C. and for a period of from about 15 to about 100 minutes.
