nickel ore recovery
US5976218A
A process for the recovery of nickel from a nickel containing ore in which the ore, particularly a laterite ore, is initially leached with an aqueous acid solution, after which the nickel is precipitated as nickel hydroxide by adding a hydroxide to the aqueous acid leach solution containing the nickel, followed by a re-leaching of the nickel with an aqueous ammoniacal

Efficient and selective recovery of Ni, Cu, and Co from low
Mar 09, 2017Low-nickel matte was intensively characterized, and Ni, Cu, and Co were determined to exist mainly as (Fe,Ni)9S8 and FeNi3, Cu5FeS4, and (Fe,Ni)9S8 and Fe3O4 (in isomorphic form), respectively. The efficient and selective extraction of Ni, Cu, and Co from the low-nickel matte in an (NH4)2S2O8/NH3H2O solution system was studied.
