Abstract

A process for obtaining a granular charge for blast furnaces from a pyrite slag, powder from the production of iron or iron ore powder, comprising: the addition of calcium chloride or ferrous chloride and calcium hydroxide or oxide calcium to pyrite slag, dye mud, blast furnace dust, open hearth furnace or converter or powdered iron ore; granulation of the resulting mixture, desiccation of the granules at a temperature below 250º C until the moisture content reaches a maximum of 5%, to raise the strength of the granule; loading and heating the dried granules in a furnace at a temperature of 900-1100º C to chloride-vaporize the metallic impurities contained therein, and subsequently heating the granules thus treated in a rotary kiln at a temperature of 1200-1250º C for a minimum 10 minutes, to produce a heated granulate having a crush resistance of 150 kg/granule or higher.
