METHOD OF TREATING FINELY DISPERSED SILICON-CONTAINING DUST FROM GAS TREATMENT OF SILICON AND SILICON FERROALLOYS ELECTROTHERMAL PRODUCTION Russian patent published in 1997 - IPC

Abstract RU 2085488 C1

FIELD: utilization of wastes. SUBSTANCE: finely dispersed dust is treated in rotatory drum, compacting of particles being effected by way of removing electrostatic charge from particles using mass exchange of material contacting with conducting surface. Silicon-containing dust is loaded in amount constituting 50-60% drum volume, linear velocity of material displacement in drum is maintained equal to 0.18-0.37 m/s, and treatment is carried out for 2-4 h. EFFECT: enhanced efficiency of process. 2 cl, 1 tbl
