Some problems of processing dispersed arsenic-containing raw materials by sublimation in vacuum

Year: 2021

Type: conference-paper

Abstract: Based on the analysis of the operation of vacuum electric furnaces for the processing of dispersed materials by sublimation of volatile components from them, developed by now, and the problems associated with technological processes, a technical solution has been proposed, in which the concentrate is moved due to rheological properties with direct heating by radiation from heater of the surface of the moving and mixing raw materials. Preliminary tests on the sublimation of arsenic sulfide compounds from the gravitational concentrate of the Nezhdaninskoye field with a particle size of 1.0 + 0.63 mm at a temperature of 700°C showed the extraction of arsenic into the vapor phase by more than 99%.
