Abstract

Abstract:

In order to explore the feasibility of leaching and reducing manganese form low?grade pyrolusite with tannic acid as reducing agent in sulfuric acid system，single factor experiment was used to study the effect of tannin acid dosage，reaction time，reaction temperature and sulfuric acid concentration on manganese leaching rate.Then the process parameters were further optimized by response surface method based on the single factor test results.The experimental results showed that the leaching rate of manganese could reach 90.86% under the conditions of the dosage of tannic acid of 3 times of the theoretical amount，the reaction time of 3 h，the concentration of sulfuric acid of 1.5 mol/L and the reaction temperature of 90 ℃.The order of reaction parameters affecting the leaching rate of manganese from large to small was as following：reaction temperature，tannic acid amount，reaction time，sulfuric acid concentration.This technology showed the characteristic of higher leaching efficiency and lower initial sulfuric acid concentration.

Key words: manganese dioxide ore, tannin acid, leaching and reducing, response surface method
