FIELD: metallurgy.
SUBSTANCE: lime or limestone are added to charge containing manganese ore and coke for obtaining slag of basicity as high, as 2.8 and charge is melted. Upon melting produced melt is refined by introduction of carbonates, chlorides and fluorides of alkali and/or alkali-earth metals or their mixtures and treated with ultra-sound of frequency equal to 18-21 kHz with separation of ferro-manganese and slag. Separated slag is cooled. Bi-water gypsum at amount of 4-6% of slag weight is added into slag which is milled to size as big, as 320 cm2/g and cement is produced.
EFFECT: raised efficiency of manganese ore processing with production of ferro-manganese and utilisation of slag for production of cement.
