Abstract
Production of manganese alloys from high-basic ores is efficient from the technical and economical point of view, if the processes of reduction and refinement in terms of carbon and phosphorus are implemented in three stages: in the first stage, saleable and process carbon ferromanganese should be produced; in the second stage, saleable and process ferrosilicomanganese should be produced using a slag-less method; in the third stage, by mixing ore-lime melt with liquid ferrosilicomanganese (17-65% Si), all grades of ferromanganese should be produced (from medium- to low-carbon lowphosphorus products).
