Improvements introduced in the object of the "continuous procedure for the benefit of pyritic arsenical ores" being characterized in that in the de-desalination stage the practically complete elimination of arsenic can be obtained by raising the temperature sufficiently and even at the expense of a large part of the pyritic labile sulfur simultaneously remove from this desarsenicaciºn stage giving a ferrous sulfide free of arsenic that is roasted in the next stage of roasting and in turn gives a few ashes and a sulfur dioxide free of arsenic so the first are for steel use in the high furnace in this aspect and the sulfur dioxide usable partly directly for certain catalysis this last according to the optional aspect foreseen in the original patent.
