In a previouswork, chemical processing of carbonate-rich latosol of Abu Thor locality have successfully recovered both of U and Cu contents by applying two successive steps of leaching processes. From the latter, the remaining two metal values; namely V and Lns were left behind in the spent residue. The latter represents the feed material of the present work for V (1050 ppm) and Lns (649 ppm ) recovery. The work involves selective leaching process for V using alkali breakdown with Sodium hydroxide (NaOH) followed by its precipitation asV2O5. The Lanthanides (Lns) left behind was then leached by using sulfuric acid followed by its precipitation as a highly pure Lns oxalate.
