Study on Leaching Manganese from Low-Grade Manganese Ores Using Different Reductants

Abstract:

This study discussed the effects on leaching rate of from low-grade manganese ore using three reductants (Hydrogen peroxide, Glucose, Cellulose). The results showed: great increase of extracting rate can be obtained in the process of leaching by adding a small amount of reductant. the leaching rate of two valence manganese can reach a maximum of 90.76%, using hydrogen peroxide as the reductant.
