Abstract

Iron bearing materials, containing the iron as oxide, are leached with an acid ferric sulphate solution; the undissolved residue separated; the leach solution hydrolysed at elevated temperatures and pressures, to convert and precipitate the ferric sulphate as the basic salt; which is then separated substantially free from the impurities of the leach solution and may be converted by usual means to the oxide. The non-ferrous metals remaining in solution can be recovered by precipitation with ammonium sulphate and the ferrous sulphate remaining in solution can be oxidized to ferric sulphate and recirculated as leaching liquor. The non-ferrous metals can be extracted from the solution by precipitation as sulphides, by normal methods and in particular by neutralizing the solution with calcium sulphide and lime.
