Beschreibung
Zusammenfassung:	Reducirajući agens koji sadrži željezo (II)-sulfat, naznačen time, da se sastoji od zelene soli i taloga koji sadrži željezo (II)-sulfat, gdje talog koji sadrži željezo (II)-sulfat sadrži željezo (II)-sulfat monohidrat koji se može dobiti postupkom koncentriranja korištene sumporne kiseline koja sadrži željezo (II)-sulfat a dobije se tijekom postupka proizvodnje titanij dioksida prema sumpornom postupku i odvajanjem sumporne kiseline iz dobivenog taloga. Patent sadrži još 18 patentnih zahtjeva. Producing reducing agent containing iron(II) sulfate comprises concentrating spent sulfuric acid and separating the sulfuric acid from the resulting precipitate. Independent claims are also included for: (a) reducing agent produced as above; (b) composition comprising cement, water-soluble metal sulfates and optionally water, containing 0.01-5 weight % of a reducing agent as above.
