Application of XRF Spectroscopy with fusion Technique in Determination of Components of Iron Ores
Introduction
As an important raw material for the metallurgical industry, iron ore is of great significance to the development of the national economy. Iron ore is a wide variety (magnetite, magnetite concentrate, hematite, siderite and vanadium ilmenite), complex components (Na, Mg, Al, Si, P, S, Ca, Mn, Ti, Co, V, Cu, Ni, Pb and other elements). The traditional analysis uses chemical separation and atomic spectroscopy. Due to the complex composition of iron ore, the sample pre-treatment is complicated and complicated. Different decomposition methods are adopted according to the type of iron ore. Because the interference elements need to be separated, the analysis is greatly reduced. speed. X-ray fluorescence spectroscopy is widely used in the metallurgical industry as a rapid, simple, non-destructive testing technique for qualitative or quantitative determination of multiple elements simultaneously [1].
Powder tableting is a common method for measuring iron ore and is widely used in the analysis of iron ore components, especially for the analysis of trace and trace elements in iron ore [2-3]. However, in actual production, iron ore has a wide range of sources, and there is a matrix effect that cannot be ignored between iron ores of different substrates, which affects the evaluation of iron ore grade. The fusing bead method [4] forms a uniform glass piece by flux to reduce the matrix effect of iron ore and the absorption enhancement effect of the element, so it is applied as an effective test method in the metallurgical industry.
