Process of preparation of elementary sulphur from an iron sulphide mineral, which comprises the oxidising acid lixiviation of the pulverised mineral, for extraction of the sulphur, the pulp obtained from the lixiviation being subjected to separation of its solids from the solution which contains it; the solids are treated hot with an organic solvent for sulphur, which is then recovered by crystallisation with cooling, while the solution is treated for extraction of the non-ferrous metals. |
