Response Evaluation of Iron Extraction to the Oxidative Action of Added Powdered Potassium Chlorate Relative to As-Beneficiated Iron Content

Abstract

Response evaluation of iron extraction to the oxidative action of added powdered potassium chlorate was carried out relative to the as-beneficiated iron content. A model was derived, validated and used as a tool for the evaluation. The model is expressed as; ζ = - 0.0008 lnϑ - 0.00001ɤ + 0.0039 The validity of the two-factorial model was found to be rooted on the expression ζ – 0.0039 = - 0.0008 lnϑ 0.00001ɤ where both sides of the expression are correspondingly approximately equal. Statistical analysis of the extracted iron concentration as obtained from experiment and derived model for each value of the mass-input of KClO3 shows standard errors of 5.19 x 10 -5 and 8.45 x 10 -6 % respectively. Furthermore, extracted iron concentration per unit mass-input of KClO3 as obtained from experiment and derived model-predicted results were 7 x 10 -5 and 6.25 x 10 -5 % g -1 respectively.
