Process of production 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 containing them; after the separation, the elementary sulphur formed by the lixiviation is melted and put into the form of agglomerates which are separated from the pulp, the agglomerates are then dissolved in an organic solvent for sulphur, which is then recovered by crystallisation with cooling, while the solution is treated for extraction of non-ferrous metals.
