The increased nickel extraction from the pre-treated ore was believed to be partly due to increased surface area created through water removal from the goethite structure during the dehydroxylation process. Nickel showed congruent dissolution with Fe, indicating that Ni was uniformly incorporated into the iron oxides structure.
