ArticleAuthor Ryabushkin M. I., +Bolshakov L .A., Yuriev A. I., Bolshakova O. V., Salimzhanova Е. V.

The improved technological scheme of fire cobalt production by a method of reduction melting in Gramolin furnace is offered by results of the spent laboratory researches and calculations. The scheme includes the separation of the material flows arriving on fusion conditioned and impure metals. It is offered to use the repetition materials with the raised iron concentrate at production of recirculated metal only. Realization of the offered actions will allow increase the cobalt yield of marks К-1А and К-1АУ by ~10 % on the basis of the existing equipment.
