Abstract
A process for extracting sulfur impurities, such as, for example, arsenic sulfide, from minerals containing such impurities, prior to its calcination, characterized by keeping said minerals in suspension in the exhaust gases of the calcination and, in case necessary, in additional hot carrier gases, conducted in the same direction or countercurrent, and volatilizing the impurities at temperatures below the point of softening of the minerals, in a temperature range between 650º and 1100º c, taking care that the gases do not contain oxygen, or an oxygen content as small as possible.
