The leaching experiments showed that the ore leaching increases with increasing acid concentration and temperature. About 78.9% of the iron ore was reacted within 120 minutes by 4M H2 SO4 solution at a temperature of 80oC. The activation energy (Ea) and the order of reaction were determined to be 31.14kJ/mol and 0.979, respectively.
