Production of manganese sulfate solution

Claim 1

A PROCESS OF PRODUCING MANAGANESE SUFLATE SOLUTION FORM FERROMANGANESE AND ORE CONSISTING ESSENTIALLY OF MANGANESE DIOXIDE, COMPRISING ADDING WATER TO AN ELECTROLYTE CONSISTING OF MANGANESE SULFATE AND SULFURIC ACID, ADDING 66* BAUME SULFURIC ACID IN AN AMOUNT NECCESSARY TO REACT WITH BOTH THE FERROMANGANESE AND THE MANGANESE DIOXIDE ORE TO PRODUCE THE CORRESPONDING SULFATES, STIRRING THE SOLUTION AND HEATING TO APPROXIMATELY 130*F., THEN ADDING TO THE SOLUTION A MANAGENESE DIOXIDE ORE, AGITATING THE SLURRY AND HEATING TO APPROXIMATELY 150*F., THEN SLOWLY ADDING TO THE HOT SLURRY FERROMANGANESE IN THE RATIO WITH RESPECT TO MNO2 OF FROM 2 TO 1 TO 1 TO 2 TO REACT WITH THE ACID TO FROM MANGANESE SULFATE AND FERROUS SULFATE AND TO RELEASE NASCENT HYDROGEN WHICH TOGETHER WITH SULFURIC ACID REACTS WITH THE MANGANESE DIOXIDE TO FORM MANAGENSE SULFATE, STIRRING THE HOT SLURRY WHILE AERATING UNTIL FERRIC SULFATE IS FORMED AND A PH STABILITY OF FROM ABOUT 2 TO 3 IS REACHED, THEN ADDING A BASIC MATERIAL SELECTED FROM THE GROUP CONSISTING OF FERROMANGANESE, MANGANESE OXIDE AND LIME TO RAISE THE PH TO ABOUT 6 TO 6.5 TO FORM IRON HYDROXIDE, ALLOWING THE SOLUTION TO SETTLE TO PRECIPITATE THE IRON HYDROXIDE AND FINALLY FILTERING AND REMOVING MANGANESE SULFATE SOLUTION.
