Recover Manganese Fluosilicic Acid Leaching

Manganese controls sulfur by forming manganese sulfide instead of iron sulfide, which would make the steel brittle. The average manganese content for all types of steel is 8.7 lb/st or 0.44 pct. The United States has no high grade manganese deposits (containing 35 pct or more manganese) and no economical methods of recovering manganese from its low grade deposits exist.
