Mining & Mineral
XRF deliver fast performance and low levels of detection for the mining and exploration industry:
- Cement is a blend of several minerals. It is critical to control the elemental composition to control properties like strength setting time, and color. EDXRF is used to analyze the raw components, the raw meal, clinker, and finally finished cement (Na, Mg, Al, Si, S, K, Ca, and Fe in Cement, Clinker, and Raw Meal).
- Limestone is the major component of cement, and is converted into lime. It is one of the most common minerals and EDXRF is a popular method for analyzing it (Na, Mg, Al, Si, K, Ca, and Fe in Lime, Limestone, and Dolomite).
- Sand is also a component of cement, but is mainly used in making glass. Low iron sand is particularly valuable for glassmaking, so it is an important sub-application (Na, Mg, Al, Si, K, Ca, and Fe in Sand and Glass).
- Clays are used in a variety of ceramic goods, bricks, and other finished products. Monitoring Ti and Fe content is important for color control, and low cost EDXRF devices can perform this analysis, while high-end EDXRF instruments can measure all the major elements (Mg, Al, Si, Ca, Ti, Fe in Kaolin and other Clays).
- Bauxite is a mineral that is high in aluminum and is the most important source of aluminum for metal production (Al, Si, Ti, and Fe in Bauxite).
- Phosphate rock is the major source of phosphorus used in fertilizer and phosphoric acid production. EDXRF is commonly used to measure the rock, phos-acid solutions, and fertilizer (P, S, Ca, Fe in Phosphate Rock and Fertilizer).
- Cemented wallboards are stronger and more durable than pressed wood wallboard. The cement components in the board are analyzed by EDXRF instrument (Na, Mg, Al, Si, and Fe in Cement Wallboard).
- Both major and minor elements in Gypsum can be measured by EDXRF (Ca, S in Gypsum).
