Mineralogical Characteristics and Quantification of Mineral Phases in Malaysian Low Grade Manganese Ore

Abstract:

The aim of this work is to study the quantification of crystalline and amorphous content of manganese ore. The mineralogical characteristics and mineral phases of Malaysian low grade manganese ore are investigated using spiking method technique. Manganese ore was mixed with an internal standard of rutile and analyzed by Rietveld refinement with SIROQUANT. The refinement qualification and quantification indicated three phases which are pyrolusite (MnO₂) with 1.1%, goethite (α-FeOOH) with 0.5% and quartz (SiO₂) with 30.9%. From the calculation, sample consisted more amorphous content which is 0.6 compared to crystalline (0.4). This revealed that the ore is in amorphous form.
