Abstract
A process for the removal of volatilizable inorganic contaminants from solid waste is provided. The process comprises the steps of: (a) providing solid waste containing volatilizable inorganic contaminants; (b) heating the waste to a temperature sufficiently high for the volatilization of the inorganic contaminants and sufficiently low so as to prevent slag formation of the solid waste, thereby producing a contaminant-rich vapor phase and a contaminant-poor solid phase; and (c) separating the solid phase and the vapor phase.
