Technical note acid leaching process by using glucose as reducing agent: a comparison among the efficiency of different kinds of manganiferous ores

摘要

The experimental results of a leaching process ofdifferent manganiferous ores are here reported. The leachingtreatment showed a satisfactory selectivity of manganeseextraction in comparison of other metals such as Al, Si and Na.XRD analyses have been done on the ores before and after the leaching treatment.The experimental results showed a good technical feasibility of theprocess which can use alternative feedstocks (containingcarbohydrates) to treat different manganese ores.
