Zinc sulphide ore has been the major source for zinc production. The process involving Roast–Leach–Electrowin (RLE) has been used to treat this kind of ores (Peters, 1992). With the depletion of zinc sulphide ores, zinc recovery from other type of ores and secondary resources attracts much attention (Rashchi et al., 2005, Gouvea and Morais ...

In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography. The final product was 91.32 ± 0.77 mg of thorium with a purity of 99.5 ± 1.2 wt%. Of that, 7.65 ± 0.10 mg was 230 Th and the remainder 232 Th.
