Abstract
The results of studies of basalt implementation in the production of chromite pellets are described with its influence on the quality of wet, dry and fi red pellets. It is shown that the use of basalt allows fully to deduce bentonite and coking fines from the charge, to reduce the burning temperature from put into practice 1400 °C to 1250 – 1300 °C, as well as to produce fi red pellets corresponding to the technical requirements.
