Implicit Assessment of Lead Extraction Based On Its As-Mined Content and Ferric Sulphate Concentration during Leaching In the Sulphate Solution

Abstract
An implicit assessment of lead extraction was carried out based on its as-mined content in galena and ferric sulphate concentration during leaching in the sulphate solution. A two-factorial empirical model was derived following computational analysis of experimental results. The model was validated and used for the assessment. The validity of the model expressed as; 3 0.0015 0.3 was rooted on the expression 0.0015 3 0.3 where both sides of the expression are correspondingly approximately equal. Evaluation of generated results indicates that for each value of the ferric sulphate concentration, the statistical analysis of the extracted concentration as obtained from experiment and derived model-predicted results show standard errors of 0.0266 and 3.04 x 10-9 % respectively. Extracted lead concentration per unit ferric sulphate concentration as obtained from experiment and derived model-predicted results were 3.35 and 3.0 ppm/ M respectively. Deviational analysis of model-predicted extracted lead concentration (from experimental result) was less than 11%. This invariably implies a derived model confidence level of above 89% as well as over 0.89 response coefficients for lead extraction dependence on its original content in the galena and ferric sulphate concentration.
