    Abstract: A process for making molecular hydrogen, elemental sulfur and sulfur dioxide from hydrogen sulfide. The process involves contacting a gas stream of hydrogen sulfide within a contacting zone with a contacting composition comprising metal sulfide in a lower sulfided state and yielding from the contacting zone a product gas stream comprising hydrogen and a recovered contacting composition comprising metal sulfide in a higher sulfided state. The higher metal sulfide is regenerated with oxygen to yield elemental sulfur and sulfur dioxide.

    Abstract: A process for the thermal decomposition of metal sulphate mixtures at temperatures from 800.degree. to 1100.degree. C. under oxidizing conditions, in which the metal sulphate mixtures are mixed with roasting residue and reacted together with fuels in the decomposition reactor to form roasting residue and SO.sub.2 -containing gases from roasting wherein the roasting residue admixed with the sulphate mixture is the finely divided fraction of the resulting roasting residue which is separated from the stream of gas in an electrostatic gas purification apparatus and returned to the decomposition reactor.This procedure has an advantageous influence on the formation of coarse roasting residue and also significantly reduces the proportion of undecomposed, water soluble sulphates in the roasting residue.

    Abstract: Pyrites tailings and smelter gas, by-products of smelters, are treated to recover iron values and elemental sulfur by a combination of: roasting the pyrites to produce elemental sulfur and iron sulfide; converting the iron sulfide with an acid cation exchange resin to liberate H2S and adsorb ferrous iron; reacting the smelter SO2 gas with a carbonyl compound to produce alpha hydroxy sulfonic acid; adding the a-hydroxy sulfonic acid to the cation exchange resin containing iron to regenerate the cation exchange resin, and recycling; heating the ferrous hydroxy sulfonate formed, to produce ferrous sulfite and liberate the carbonyl compound; calcining the ferrous sulfite to liberate SO2, producing by-product ferrous oxide, and reacting the liberated SO2 with the liberated H2S to produce elemental sulfur.
