Metal oxides in nickel ore

AppNote 1366: analysis of important metal oxides in nickel ore is demonstrated using the empirical approach.

Background

During site characterization and preparation for smelting, it is important to determine concentrations of various metals in nickel ores. While NiO and Fe₂O₃ are the most important metal oxides, TiO₂, Cr₂O₃ and MnO may also be present in significant quantities. Characterizing the ore is important to determine potential yield, as well as during extraction and smelting. EDXRF is an excellent tool for mine site exploration and characterization, and can be used throughout the processing steps, extraction and smelting to measure the ore material, concentrate, matte, filter cakes and slags.
