• The results of studies on the production of pellets for the metallurgical stage based on manganese concentrate with a manganese content of 34 %, obtained from waste manganese-containing sludge, are presented. Kaolin and highiron diatomite in combination with calcium oxide and coke were tested as binder components of charges. Manganese- containing pellets were produced by composition pelletizing in a Eirich high-speed mixer-granulator. The size of pellets in the form of rounded granules was in the range of 5 - 10 mm. Sintering roasting temperature of pellets was 1150 - 1200°C. Strength of roasted pellets was 1 313 with kaolin as binder, 1 940 with diatomite, and diatomite with lime addition – 2058 N/pellet respectively.
