ENVIRONMENTAL IMPACTS OF THE INTERGRATED DRY GRANULATION METHOD APLICATION OF FERONICKEL SLAG

Abstract: Metallurgical industries rentable and responsible towards the environment among the key objectives put the development of utilization schemes of all of its middle – products. The smelting process of nickel oxides ores, is almost slag process, where about 75% of the calcine pass to slag. In the New Ferronickel smelt plant in Kosova, produced slag is thrown in the landfill without adequate proper treatment. Such exploiting concepts, without any valorisation strategy, have resulted with the no effective manufacturing cost, irrational use of resources and high concentrations of polluting components. This slag represents the mid - product, with the high value effects in economy and environment. Developed research in terms of opportunities to use it, verify that the application of the integrated dry granulation method will transform slag into a resource with corrected qualities (composition and properties - by adjusting it in the valuable aggregate for cement products, asphalt concrete and all other of the construction industry). In renewable energy source, through returning it in production process and reduce its pollution impacts.
