Abstract
The recovery of nickel and cobalt from the ferriferrous laterite ores of the Buruktal deposit via a hydrometallurgical processing scheme for the reduced ferriferrous oxidized nickel (limonite) ore with weak sulfuric acid solutions is studied. An ammonia reagent (NH4)2SO4, which forms Ni and Co complexes, is used to enhance the leaching selectivity. The possibility of decreasing the consumption of H2SO4 and intensifying nickel and cobalt recovery at increased pH of the solution (pH 3.0–5.0) and recycling of sulfuric acid solutions is studied.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
