A process for the pyrometallurgical treatment of sulphide iron ore or iron ore concentrate by oxygenated gases, forming a melt containing iron, sulfur dioxide and, eventually, volatile non-ferrous metals or non-ferrous metal compounds at temperatures of at least 1100 degrees c, characterized in that the iron ores or iron ore concentrates are introduced, in several places and in each case in the direction of a tangent or secant, into a cyclone chamber with approximately horizontal axis, cooled by evaporation of water at a pressure of at least ten atmospheres, being reacted with gases rich in oxygen and without the addition of fuel, or with only a very small addition, in such a way that a mineral is produced with a ratio atomic average of fe: s = 1: (0.70-0.90).
