采矿过程优化with XRF
从地面提取的矿石的质量永远不会恒定。这使得对原始材料（有时是部分处理的材料）进行了频繁监控，成为所有采矿项目的关键部分。
X-Ray Fluorescence (XRF) is the most accepted analytic technology for grade control in mineral production and processing. Bruker’s wide range of XRF instrumentation can meet any need in production monitoring for mining in the goal of separating waste form ore. XRF works by measuring the secondary x-ray fluorescence generated by elements when they are excited by a primary x-ray source. The XRF analyzer can measure the elemental concentration in rocks. The elemental concentration can be used to identify grade, sub-grade and waste and prevent the dilution of ore by waste rock. The advantages of XRF include:
XRF is fast, analyzing all elements from a single spectrum
Analyze a wide range of elements from carbon to americium
Measure concentration of elements from trace (ppm) to 100%
简单而快速的样品准备
Easy process automation and incorporation of robotic sample changes
核心非破坏性元素分析的可能性

Bruker’s experts can help design a measurement program that:
Provides mission-critical geochemical data quickly from any point in the mine lifecycle or commodity value chain
有适当的样品准备，包括制浆
使用矩阵匹配的校准
Includes a robust QA/QC protocol including sample duplicates, blanks and reference standards
通过互补方法（例如WDXRF）验证至少10％的结果的验证
根据验证结果更新校准，并重新计算数据以随着时间的推移而变得更加准确
总反射XRF
Total Reflection X-ray Fluorescence Spectrometers
Total reflection XRF (TXRF) is an emerging method for aqueous geochemistry, powders or digested rocks in mining. Detection limits down to ppb range can be achieved on small samples with no dilution, no consumable gas and simple sample preparation. TXRF is an ideal method for testing effluent, runoff, pit water, soil and other wastewater for heavy metals like cadmium (Cd), mercury (Hg) and selenium (Se). For example, mercury can be analysed in water with good precision when concentration levels are above about 30 µg/l. Bruker offers two models of TXRF:
S2 Picofox是单个激发源25样品TXRF与实验室一样在家的现场。测量铝（Al）的铀（U）
S4 T-Star是一种决斗激发源，高通量90样品TXRF，用于从钠（NA）到铀（U）的测量，这是全周期表的最终工具
