Metal removal from industrial waste by hydrochloric acid

Leaching of metals from industrial solid waste in hydrochloric acid, HCl solution was studied. In this study, the significant of parameters such as HCl concentration, temperature, liquid to solid ratio and leaching time on the removal percentage of metal impurities were investigated using response s...
