Manganese Ores from South Sulawesi: Their Potential Uses as Raw Materials for Metallurgical Industry

Abstract

.2 wt%). Relatively higher grade of Fe 2 O 3 in the Barru ore implies that it has potential application for ferromanganese production; whereas the elevated SiO 2 content of the Bone ore is a good indication for silicomanganese manufacture. However, both ores may not favorable to be directly used as raw materials in metallurgical uses. Prior to be used, the ores should be treated by applying physical beneficiation in order to reduce deleterious elements.
