The method also comprises mixing the solution (22) with a precipitation agent (31), thus forming a second mixture (32) in which the sulfate and/or oxysulfate precipitates and is removed (301), heated, reduced and decomposed (400) by means of a reducing agent (41) selected among elemental sulfur, hydrogen and a reducing flame, thus obtaining SO 2 (42) available for making H 2 SO 4 , and a solid oxide (43) of the metal of the alkaline reagent that is recycled (101) as alkaline reagent (10) in the step (200) of mixing with the waste material (20). Advantageously, a step (350) is provided of recovering precipitation agent (31) from the water of second mixture (32), after removing (301) the sulfate and/or oxysulfate, and a step (351) is also provided of recycling the regenerated precipitation agent (31), In particular, an alcohol as ethyl alcohol, used as the precipitation agent (31), can be easily regenerated by distillation, exploiting low temperature-heat, which is largely available from a possible sulfuric acid production plant close to the plant that producing the sulfuric waste material (20). The method according to the invention makes it possible to eliminate the sludge resulting from the sulfuric waste material treatment, while recovering valuable compounds.

摘要： Process (1) for making iron sulphate comprising a first reactor (30) in which a starting solution containing sulphuric acid is supplied (11, 12) in a measured concentration. The starting solution is caused to react with iron scale put into the first reactor (30). At the end of the reaction an intermediate solution is obtained comprising iron sulphate and ferric sulphate that is supplied (12) in a second reactor (31) where it reacts with scrap iron in it present. Here, ferric sulphate developed in the intermediate solution reacts with the scrap iron and turns into iron sulphate whereby in the solution resulting the iron sulphate is the only iron based compound. From the reactor (31) the intermediate solution is then transferred (13, 41, 14) to a crystallizer (35) having a stirrer and connected (23) to a vacuum system (60). Once achieved the predetermined temperature, the final solution is given (15, 42, 16) to a centrifugal machine (36) in which the separation is obtained of the mother water from crystals of iron sulphate heptahydrate. The mother water is then sent (18) to a reservoir (37) and then cycled (20, 43, 21) upstream of the process (1) by a pump (43) [Figure 1].
