摘要：

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)(2)SO4, 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.
