On the possibility of carbonaceous dust waste use of prebaked anode production in silicon metallurgy

Year: 2018

Type: conference-paper

Abstract: During the prebaked anodes production used in aluminium electrometallurgy a considerable amount of fine-dispersed waste with a carbon content of more than 90% is formed. Analytical studies of the waste properties such as chemical, particle size analysis, moisture content and some others have been conducted. Electro-paramagnetic resonance (EPR) method was used to study the structures of charcoal, oil coke and a sample of carbon-containing dust from mixing and pressing compartment of aspiration equipment. EPR results showed that the studied sample is similar in structure to natural traditional reductants (its EPR spectrum has a pronounced narrow Gaussian signal). This indirectly shows its satisfactory reactivity and can be recommended as an additive (in pelletized form) to the charge for the silicon production
