Establishing the Optimal Parameters for the Aqueous Oxidation of Sulphurous Concentrates with Lead Content

Abstract:

The paper presents the results of the mathematical modelling for the oxidation process (in autoclave) of sulphurous concentrates with lead (PbS containing), in weak alkaline aqueous medium. Using an active program of experiments (an order two orthogonal program, PO2), the optimal conditions were established in order to run the process in a manner that will lead to obtaining a maximum oxidation yield of sulphides from lead concentrates. Preliminary research and studies indicated four parameters (temperature, process duration, oxygen partial pressure and L:S ratio) that have a significant influence on the performance of the oxidation process, which we define as the oxidation yield of the sulphides in concentrate. The optimal values of the oxidation process parameters are: T = 138oC, t = 2.53h, pO2 = 4.78 atm and L:S ratio = 15:1. Keywords: mathematical modelling, oxidation process, parameter optimization, sulphurous concentrates
