PROCESS FOR THE ELECTROLYTIC REDUCTION OF FERRIC IONS IN A SULFURIC SOLUTION FOR LEACHING LEGEND

摘要

A PROCESS FOR REDUCING FERRIC IONS IN A SULFURIC ILMENITE LEACHING SOLUTION. /P P A SULFURIC SULFURIC CATHOLYTE SOLUTION OF AN ILMENITE LEACHING IS CIRCULATED IN A SEPARATE ELECTROLYSIS CELL COMPARTMENT ANODIC COMPARTMENT THROUGH A LIQUID-IMPERMEABLE ION EXCHANGE MEMBRANE, A FERROUS SULFATE ANOLYTE SOLUTION IS CIRCULATED IN THE ANODIC COMPARTMENT OF THE ELECTROLYSIS CELL AND AN ELECTROLYSIS CURRENT IS APPLIED TO REDUCE THE FERRIC IONS IN THE FERROUS ION CATHOLYTE AND TO OXIDIZE A PORTION OF FERROUS IONS IN FERRIC IONS IN THE ANOLYTE. /P P THUS PREVENT THE FORMATION AND RELEASE OF OXYGEN IN THE ANODIC COMPARTMENT AND THE THE ELECTROLYSIS DEVICE MAY BE USED OUTSIDE HOURS OF THE HIGHEST TIMES TO REDUCE ENERGY CONSUMPTION AND LOWER OR SUPPRESS FERROUS SULFATE AS A SECONDARY PRODUCT DURING THE PREPARATION OF TITANIUM DIOXIDE.
