Abstract

A method for the manufacture an additive material for the production of crude iron which comprises charging an iron sulphidic material to a furnace space together with oxygen and a silicate-containing material in relative proportions such that it is possible to obtain an iron silicate melt containing 60-90% by weight iron, calculated as iron (11) oxide when melting. The melt is granulated or permitted to solidify and then crushed to pieces of a size suitable to charge to a furnace unit for the production of crude iron.
