XRF analysing manganese and iron

Use of XRF Analyser in Mn-Fe Exploration and Mining

Manganese (Mn) is not a rare metal as it makes up about 0.1% of the earth’s crust. Also average Mn in soil is about 440 ppm (ranges from 7 to 9000 ppm depending on soil type). These concentrations are much higher than the detection limit of Mn; therefore, Mn can easily be detected by Thermo Scientific portable XRF analysers.

Manganese ores usually consist of dark brown to black oxides particularly pyrolusite (MnO2) and psilomelane (BaMn9O18 2H2O). Manganese carbonate (rhodochrosite, MnCO3) and silicate (braunite, MnSiO3) may occur locally. All manganese minerals usually show a close spatial relation to the iron ores.

Manganese is mined in countries such as South Africa, Australia, China, Brazil, Gabon, Ukraine, India, Ghana and Kazakhstan.
