Abstract

To produce manganese containing ferroalloy for steel production, an agglomeration mixture is produced which comprises chromite ore concentrate and manganese ore fines with a grain size smaller than 6-9 mm. The mixture is agglomerated to produce green agglomeration products, such as pellets or other types of agglomerates. The green agglomeration products are sintered in a steel belt sintering furnace to produce either sinter or sintered pellets. The sinter or sintered pellets are smelted in a submerged arc furnace to produce manganese and chromium containing ferroalloy. The ferroalloy produced by the method comprises 6.0-35 w-% manganese and 31-54 w-% chromium.
