Abstract

A study of the lixiviation of Manganiferrous Aluminosilicate Mineral in hydrochloric acid has been undertaken. Experiments on quantitative lixiviation of the mineral showed that its dissolution rate depends on hydrogen ion concentration, reaction temperature and particle size. The activation energy calculated from the experimental data was 34.19 kJ/mole and this suggests a diffusion controlled mechanism. A reaction order of 0.2 with respect to the acid concentration was also found. With 8.42 M HCl at 80°C, about 69.27% of the 10 g/L of the manganiferrous mineral was dissolved within 120 min using < 0.09 mm particle diameter.

 

Key words: Manganiferrous, lixiviation, dissolution, kinetics, hydrochloric acid.
