Optimal analysis for leaching of lead from processed anode slime

Abstract

The leaching of lead from the treated anode slime with triethanolamine (TEA) was investigated by using full factorial and orthogonal design techniques. The effects of TEA concentration, solid/liquid ratio, temperature, and contact time on the leaching process were evaluated to determine the interactions between the parameters. The major factors for the system were found to be TEA concentration and reaction temperature. The highest recovery is obtained at process conditions of 3.5 M TEA concentration, reaction time of 150 min, solid/liquid ratio of 1/10, and a temperature of 313 K. A polynomial model between the important parameters and response was deduced using variance analysis at 95 % confidence level. The analytical performance for measurement at the point of optimum by this technique was found to be superior and more proper than that of one variable at a time.
