Abstract:
The smelting process of nickel oxides ores in the electric furnace is almost slag process, where about 75% of the calcin pass to slag. The designed capacity of the New Ferronickel foundry has possibility to process about 1.200.000 t ores /year, capacity production to produce 11.000 t Ni/year, and 800.000 t slag / year. Until now, about 8 million tons of slag is stored in slag landfill. The stored slag is highly prized raw material for: construction industry, cements industry (portland cement with slag as additive, metallurgical cements), refractory materials, mineral glasses, bituminized aggregates (asphalt concrete, pavement for paths, etc.). Nowadays this slag landfill is not properly treated and it is one environmental problem. The examination of the Ferronickel slag, show that in addition to numerous opportunities for their valorisation, but excite as well and the limits on the use of such slags as: balance of slag ingredients (CaO-FeO-SiO2, MgO-FeO-SiO2), structural properties of SiO2 and silicate ions, water granulation, granules composition, mass volume, plasticity, water absorption, etc. These slag limits are research object in research laboratories: Xella-Kosovo, "Ahn Group Handles" - Prishtina, “Ramtech” - Zagreb, “Silkapor” – Kosovo, etc, and results obtained are presented in this paper.
