Goethite Precipitation
Iron removal can be in precipitation by Goethite process.In lateritic Nickel ore, the iron precipitate can be produced using Goethite process.
Lateritic Nickel Ore.Silicate-rich
limoniteRemoval of iron via goethite process can be effected by the Vielle Montgane(V.M) technique and famous into commercial application in the Zinc Industry.Example Chemical Reaction(V.M)
Ferrous ion oxidation= 2Fe3+ + 0.5O2 + 2H+ =2Fe3+ + H2O Ferric ion hydrolysis= Fe3+ + 2H2O = FeOOH + 3H+Total reaction= 2Fe2+ + 0.5O2 + 3H2O = 2FeOOH + 4H+
