Indium is associated in trace amounts in several kinds of zinc and aluminum ores and has therefore been recovery as a byproduct in these industries Together with this metal iron is found in high concentration The present work investigates the separation of indium and iron by solvent extraction using a Replicate Two-Factor Factorial Design

c Roasting: The concentrated ore is roasted in the excess of air at a temperature of 900 degree celsius in the reverbatory furnace So the ore reacts with oxygen to form Zinc Sulphide (ZnS) and Sulphur dioxide (SO 2) which is given by the reaction below $$ce{2ZnS + 3O2-[{heat}] 2ZnO + SO2}$$
