  ABSTRACT: Model for the calculation of the concentration of dissolved haematite during hydrogen peroxide leaching of iron oxide ore has been derived. The model was found to depend on both the % concentration of dissolved iron and weight input of iron oxide ore from experiment. The validity of the model is rooted on the expression %Fe2O3 ≈ %Fe√(μ)1/3 where both sides of the relationship are correspondingly almost equal. The deviation of the model-predicted concentration of dissolved haematite from the corresponding experimental values is less than 30% which is quite within the acceptable range of deviation limit of experimental results. The model indicates that the dissolved % ratio of extreme oxidation stage of iron to that of its extreme reduction stage is approximately equal to one-sixth (1/6th) power of the weight input of iron oxide ore during the leaching process.
