Abstract:
Newco Ferronikeli of Drenas was privatised in year 2006, production process has started in year 2007 with first technological line, while second technological line in year 2008 and is operating very successfully till now. During continuously efforts of improvements in metallurgical process of obtaining Fe-Ni was achieved to be recycled converter slag and eliminated at all adding of limstone in charge of Rotary Kiln.The positives effects which have been achieved in calcinations process of Rotary Kiln are: reducing of consumption of mazut, reducing of sticking of calcine in calcinations area, increasing of temperature of rousted material, increasing of recovery of Ni, increasing of pre-reduction of rousted material and increasing of capacity of Rotary Kiln.Into Electric furnace was produced a slag with lower acidity and lower smelting point and better cast ability, improving smelting process of production Fe – Ni as well.Except improvement to the metallurgical process of obtaining Fe-Ni, has been decreased the pollution of environment as well, producing less CO2 in rotary kilns and electro-reduction furnaces.
