Основным восстановителем служит коксик - подрешетный Продукт (-5 мм) от грохочени  Губехинского кокса, сульфидизатором - гипсова  пыль. Общий расход восстановител  5 абс. %; сульфидизатора 10 абс. %. Пылевынос не превышает 2%. В ходе плавок получают штейны следующего химического состава , %: Ni , Со 0,2-0,5; Fe 55-70; остальное сера. Извлечение в штейн Ni 88%; Со 65%.general,,%:, Ni 1,5-1,26; Co 0.04-0.05; Fe 16.0-20.0; SiO2 40.0-49.0; CaO 1,2-.2,0; MgO 7.6-11.2; AlsOg 6.0-9.0; C 6.0-8.0; S 0.3-1.9. The main reducing agent is coking, the undersize product (-5 mm) from the screening of Gubehinsky coke, and the sulfidizing agent is gypsum dust. The total consumption of the reducing agent 5 abs. %; sulfidization 10 abs. % Dust removal does not exceed 2%. During the heats, mattes of the following chemical composition are obtained,%: Ni, Co 0.2-0.5; Fe 55-70; the rest is sulfur. Extraction to Ni matte 88%; With 65%.
