Red mud, SPL (spent pot lining), fly ash from aluminium industries; scrap, slag, dross, reverts, slime, flue dust, mill scales, sludge, etc. from copper industries; zinc tailing, slag, leach residue, jarosite residue, etc. from zinc industries, and BF (blast furnace) slag, flue dust, ISF (imperial smelting furnace) slag, etc. from lead industries are the major solid wastes generated from the process. Common practices of waste management in these industries are recycling and recovering the metal values and dumping. The presence of toxic elements in some of the solid wastes can cause environmental degradation while dumping. Stringent pollution control rules are being enacted and implemented as a result of which all the metal-producing industries in the organized sector are now taking care of the environment and waste management related problems, but pollution from unorganized lead units is the major cause of concern. Permissible limits of toxic constituents in zinc-based secondaries and threshold zinc concentration for both indigenous and imported raw material were worked out at the NML (National Metallurgical Laboratory) and based on these results a recommendation to the Ministry of Environment and Forests, Government of India, was made to specify the permissible limits for the import of zinc secondaries. An overview of the attempts made to recycle/ recover metal values and production of value-added products, at NML are also mentioned in the text.(13 tables, 40 references)
