Abstract
A process for manufacturing ferric sulfate has the steps of introducing water into an interior of a pressure vessel, introducing an iron material into the interior of the pressure vessel, mixing the iron material and the water within the interior of the pressure vessel, adding sulfuric acid to the mixed iron material and water, agitating the iron material and the sulfuric acid and the water for a period of time so as to increase a temperature of a reaction and a pressure of the reaction within the interior of the pressure vessel, and discharging ferric sulfate from the interior of the pressure vessel. The iron material can be either hematite or magnetite. Oxygen can be introduced into the interior of the pressure vessel if the iron material is magnetite.
