ABSTRACT
In order to research the pre-reduction increase rate in rotary kilns at New Plant in Drenas Ferronickel, and to determine the factors affecting the pre-reduction increase rate of the nickel ore, we carried out two experiments with the nickel ore temperatures of 800 °C and 900 °C in laboratory rotary furnace "Linder", in the laboratory of Fe-Ni Kavadarc, Macedonia. Two samples of ore and auxiliary content were developed based on industrial reports, at the laboratory Ferronickel in New Plant in Drenas. Load composition was: ore 96.66% and 3.33% calcine, auxiliary materials by 12% each charge. Ore origins had this percentage: 56.66% Cllavice; Albania 20% and 20% from the PhilippinesAs auxiliary material we used two types of lignite on 12% share in the mixing charges: moist lignite of Kosovo on 9% and coal with 3% stone Indonesia. In experiments performed in the laboratory the team have achieved comparable results by comparing the results of the Industrial Plant of ferronickel in Drenas. We have been able to determine the factors affecting the growth rate pre-reduction nickel ore and as a result metallurgical process have improved.
