magnetite iron peak

Magnetite

Due to its high iron content, magnetite has long been a major iron ore. It is reduced in blast furnaces to pig iron or sponge iron for conversion to steel. Audio recording using magnetic acetate tape was developed in the 1930s. The German magnetophon utilized magnetite powder as the recording medium. Following World War II, 3M Company continued work on the German design. In 1946, the 3M researchers found they could In summary, Iron Peak presents MGT with an outstanding opportunity to process high-quality mineralisation early in the Project, reducing technical risk, Iron Peak Mineral Resource Significantly Improved Magnetite

Therefore, when this analysis was carried out, the X-rays reflected off the iron compound to give peak amplitudes that helped to identify the elements present in the compound being studied. The peak amplitude of iron started from approximately 0.66 to 7 keV, as shown by Fig. 2 d and f which confirmed the presence of the iron elements in Peak Iron has significant hematite and magnetite iron ore resources that are undergoing continuous exploration and assessment.
