Кристаллизация с высокой скоростью обеспечивает образование ультрадисперсной структуры и стабилизацию нестехиометрических высокотемпературных фаз, что ведет к увеличению реакционной способности гранул при последующей гидрометаллургической переработке. В растворе серной кислоты электролизом гранулированного медно-никелевого файнштейна, имеющего соотношение меди к никелю, равное 1 : 1, на катоде выделен порошок меди, а на аноде – серосульфидный (NiS–Сu9S5–Cu7S4–S) шлам. Оценено влияние плотности тока и продолжительности процесса на показатели электролиза и качество выделяемого медного порошка. Серосульфидный шлам (содержащий более 50 % серы) образует на поверхности гранул пассивирующий слой, препятствующий подводу реагентов и отводу продуктов реакций из зоны взаимодействия. При анодной плотности тока до 100 А/м2 обеспечен перевод металлов в раствор и формирование на катоде медного порошка, отвечающего марке ПМС-1. Порошок представлен частицами дендритной и осколочной форм размером от 1 до 100 мкм. Качественный медный порошок образован при насыщении электролита по никелю до 28,0 г/дм3 . Анодный выход по току по сере равен 37 %, а катодный по меди – 92,8 %. Процесс рекомендован для разделения меди и никеля при переработке сульфидно-металлических сплавов. Содержание меди в растворе в ходе электролиза колебалось в пределах 0,4–2,0 г/дм3 .</p></abstract><trans-abstract xml:lang="en"><p>The paper justifies the method of processing sulfide-metal melts including their granulation and subsequent electrolysis of granules. High-speed crystallization ensures ultrafine structure formation and stabilizes non-stoichiometric high-temperature phases leading to an increase in the reactivity of granules during subsequent hydrometallurgical processing. Copper powder was isolated at the cathode, and sulfur-sulfide slime (NiS–Сu9S5–Cu7S4–S) was isolated at the anode in a sulfuric acid solution during the electrolysis of granular copper-nickel matte (Cu : Ni = 1 : 1). The influence of current density and process duration on electrolysis parameters and the quality of copper powder isolated was estimated. Sulfur sulfide slime (containing more than 50 % sulfur) forms a passivation layer on granule surfaces, which prevents reagent feeding and reaction product removal from the interaction zone. Anodic current density of up to 100 A/m2 ensures metal conversion into a solution and copper powder (PMS-1 grade) formation at the cathode. Powder is represented by 1 to 100 μm particles of dendritic and fragmented shapes. High-quality copper powder isolation was achieved when saturating electrolyte with nickel to 28,0 g/dm3 . In this case, anode efficiency was 37 % with respect to sulfur, and cathode efficiency was 92,8 % for copper. The process is recommended for copper and nickel separation when processing sulfide-metal alloys. Copper content of in the solution during electrolysis ranged from 0,4 to 2,0 g/dm3.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>файнштейн</kwd><kwd>грануляция</kwd><kwd>сульфиды</kwd><kwd>медь</kwd><kwd>никель</kwd><kwd>сера</kwd><kwd>электролиз</kwd><kwd>электрохимическое окисление</kwd><kwd>плотность тока</kwd><kwd>электролит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper-nickel matte</kwd><kwd>granulation</kwd><kwd>sulfides</kwd><kwd>copper</kwd><kwd>nickel</kwd><kwd>sulfur</kwd><kwd>electrolysis</kwd><kwd>electrochemical oxidation</kwd><kwd>current density</kwd><kwd>electrolyte</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Чижиков Д.М., Гуляницкая З.Ф., Плигинская Л.В., Субботина Е.А.
