  • Preparation of Ferrous Sulphate

    Iron shows two oxidation states – Ferrous and Ferric. 1 Ferrous sulphate is otherwise known as "green vitriol" and used as a reducing agent in chemistry. For the preparation with sulphuric acid the very first step is to determine the amount of rmpurty as sulphuric acid tolerable by the crystals which may result in chemical burns on touching if the amount of sulphuric acid content will be ...

  • DISINTEGRATION OF SCRAP ALLOYS TO FACILITATE RECOVERY .

    In the treatment of ferronickel for example, the alloy is ground to a fine powder then leached in aqueous oxygenated ammonium sulphate or sulphuric acid for extraction of nonferrous values. These known processes are generally unsatisfactory for extraction of contained nickel, cobalt and copper values from ironchromium scrap alloys.

  • Scrap use in the steel industry

    While iron ore supply can flex with demand, the availability of scrap is mostly fixed, a function of steel demand and arising of scrap at the end of life of steel products, equipment and facilities. worldsteel estimates suggest that global endoflife ferrous scrap availability stood at about 400 Mt in 2019. We expect that global endoflife scrap
