Abstract
The paper summarizes the results of numerous works performed by the employees of the Pobuzky Ferronickel Plant, the Department of Electrometallurgy of the USU of Science and Technology (Dnipro), RPC «Technosplavy» under the leadership of Mykhailo Hasyk, academician of NASU. A technology of low iron recovery has been implemented at the plant, which allows producing high-percentage black ferronickel, containing 30…50 % Ni, and almost hundredth fractions of carbon and silicon, directly in electric furnaces. The thermodynamic features of off-kiln ladle desulfurization of ferronickel with soda are considered. A complex technology has been developed and implemented, which involves mixing crude ferronickel produced in one furnace with a reduced silicon and carbon content (up to 0.01 %) and a high nickel content (over 50 %) with an alloy from another furnace with a low nickel concentration (10…17 %) and a high concentration of silicon and carbon, which are so necessary for desulfurization with soda in a ladle. The developed and proposed technological schemes for the enrichment of electric furnace slags using the «wet» technology and refining slags using the «dry» technology make it possible to recycle about 1,200 tons of nickel per year, or to extract 31.6 % and 94.65 % of nickel from the slags, respectively. 19 Ref., 4 Tabl., 3 Fig.
