| description | FIELD: metallurgy.SUBSTANCE: invention refers to the recovery of secondary metal scraps, in particular, to processing of metal scraps of nickel-based heat-resisting alloys (superalloys). Method of recovering nickel from nickel-based heat-resisting alloys by electrochemical processing involves anodic dissolution of the alloy at anodic polarisation by pulse current at constant potential in nitric acid electrolyte. The anodic dissolution is carried out at nitric acid concentration of 100 g/L at fixed value of the anode potential equal to 1.0-1.2 V. As a result the cathode product - nickel concentrate with the purity of at least 95% per one stage - is obtained.EFFECT: processing of nickel-based heat-resisting alloys producing nickel concentrate of high purity.3 ex
Изобретение относится к регенерации вторичного металлического сырья, в частности к переработке металлических отходов жаропрочных сплавов на основе никеля (суперсплавов). Способ извлечения никеля из жаропрочных сплавов на основе никеля электрохимическим методом включает анодное растворение сплава при анодной поляризации импульсным током при постоянном потенциале в азотнокислом электролите. При этом анодное растворение ведутпри концентрации азотной кислоты 100 г/л при фиксированном значении потенциала анода, равном 1,0-1,2 В. В результате получают катодный продукт - никелевый концентрат чистотой не менее 95% за одну стадию. Техническим результатом является переработка жаропрочных сплавов на основе никеля с получением никелевого концентрата высокой чистоты. 3 пр. |
