  • Quantitative Determination of Metals in Waste

    2018-9-11 · Dross is produced during Aluminium melting processes [3-4].Typically 1.5-2.5 % of dross are generated per metric ton of molten Aluminium while processing. It has become an area of interest to the Aluminium producers & secondary processors due to large production of Aluminium metal and dross as well. Mainly dross contains metallic Aluminium and Aluminium oxide and some impurities. The recovery of metal from dross is carried out by conventional metallurgical process all over the world. It is generally considered that dross is a process waste and disposed to sub-contractor after recovery of metal from it. In the present communication, a methodology of sample preparation, determinations of metallic Aluminium using both classical and ICP-AES methods have been used.
