ABSTRACT
The leaching behavior of solution
was studied. The sourced sample was pulverized and the chemical characteristic
determined. The results of the chemical analysis of the ore based on AAS
revealed that the ore contained 31.75% Pb, 0.93% Zn, 0.525% Cu, 0.165%Mn,
0.0702% Mg, 0.0202% Ca, 9.23% Fe and 0.0056% Ni. The mineralogical analysis by
X-ray diffraction technique revealed that the ore contained galena and other
associated minerals. The results showed that the leaching of lead from galena
concentrates increases with concentration, temperature, stirring speed,
solid liquid ratio and a decrease in particle size increased the leaching rate
positively. The study, also showed that complete dissolution of lead was
achieved at 70oC, while other parameters were fixed. It was found that
mixed kinetic is the controlling mechanism for this study. The was
determined to be 37.57kJ/mol. The reaction order and Arrhenius constant were
calculated to be 0.179 and ,respectively.
