Abstract
A method for toasting a sulphurous ferrous material, such as raw pyrites in grain and flotation concentrate, in two stages in turbulent layer bed reaction devices, with the material being roasted in the first stage to at least 5% residual sulfur, and preferably at least about 15% and at most about 38% residual sulfur, at a temperature of more than 800º c, and preferably of more than 900º c, characterized in that the material is then transferred, still hot, to a second stage and roasted to substantially magnetite, in a known manner, at a temperature lower than that of the first stage, between 700 and 850º c, after which the material is optionally magnetically enriched.
