FIELD: waste processing methods.
SUBSTANCE: method is characterized by that waste with content of nickel from 10% and higher and content of aluminum from 30% and higher is melted, conducted through nozzle and dispersed in the form of molten droplets in a cooling reagent. Resulting powder is subjected to magnetic separation to separate into magnetic and nonmagnetic fractions, The former is oxidized by firing it and then oxidized magnetic fraction is mixed with slag-forming components and above-mentioned nonmagnetic fraction powder. Resulting mixture is treated to perform aluminothermal reduction of nickel.
EFFECT: enhanced waste processing efficiency.
