Reductive Acid Leaching of Low Grade Manganese Ores
Citric acid leaching was high at 2 M about 40% after 6 days and decrease in concentration . i.e. at 1 M, 0.5 M, 0.25 M, 0.1 M concentration leaching were found to be 29%, 18%, 10%, 7% respectively (Figure 3). Our study emphasizes on the leaching of low grade manganese ores with minimal concentrations of both the organic acids.
