  • METHOD FOR THE PRODUCTION AND THE PURIFICATION OF MOLTEN CALCIUM ALUMINATE USING CONTAMINATED ALUMINUM DROSS RESIDUE
    Publication number: 20140224069
    Abstract: The present invention provides a process for the preparation of pre-melted calcium aluminate for iron and steel treatment and protection by the fusion of aluminum dross residues, usually referred to as non-metallic products (NMP) containing variable levels of aluminum (Al) and aluminum nitride (AlN) with calcium carbonate at high temperature, under oxidizing atmosphere. It further relates to the purification of the molten calcium aluminate from some contaminants present in the dross residue.
