Due to the fact of the added uncertainties and lack of relevance of the higher Fe concentrations, only experimental data for Fe concentration within 200 µM at pH two.eight is shown in the figure. For every grid , we run the model for every single Fe or Cu concentration for which we have a measurement and calculate a mean squared error. The MSE of every single unit square is obtained by averaging the MSEs of the nearest 4 grid points. Soon after the original source one particular cycle, we arrive at a unit square centered by a minimum MSE and we then divide this square into a new 11 × 11 grid field. The range containing the minimum MSE is narrowed as this procedure is repeated, and right after four instances the rate constant combination with minimum MSE is determined to be the most effective fit.

Oxide ores are placed onto a leach pad and saturated with weak sulfuric acid solution that dissolves the copper mineral content.
