Abstract

Process for the manufacture of magnetitic granules, which are especially suitable for direct reduction and reduction in vat kilns, by roasting raw or crude granules made from iron ores, characterized in that the raw granules made from minerals predominantly magnetitic iron, optionally with the addition of binders, are calcined in a gaseous atmosphere, containing at most 5% by volume of free oxygen, at temperatures that are 50 to 200ºC below the temperatures necessary for the manufacture of hematitic granules with a compressive strength of approximately 200 kg/granule, under oxidizing conditions, from the same raw materials.
