铝土矿采矿和铝制加工
Introduction
Bruker的分析技术有助于满足生产目标，确保铝业的质量并节省成本
Bauxite ore is the leading source for aluminum. Bauxite is a hydrated aluminum oxide in the form of gibbsite, boehmite or diaspore that forms through surface weathering and direct chemical precipitation. Surface processes introduce a complexity and diversity of ore and impurity compositions that requires careful consideration of analytical technology when designing exploration, grade control, and process control workflows. Bruker’s analytical tools empower all phases of bauxite mining from exploration to remediation.

Bulk Mineral Analysis
Bulk Mineral Analysis
XRD直接测量矿物学。了解铝土矿中粘土或氧化铁等矿物质杂质是氧化铝炼油厂中受益的关键，从而减少残留物。在冶炼厂XRD中测量凝固的电解质的矿物学。导出控制参数，对于管理冶炼单元的操作是必不可少的。此外，通过XRD监测阳极质量。
Microanalysis and Automated Mineralogy
Microanalysis and Automated Mineralogy
自动化的矿物学结合了影像的力量scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS) to generate mineral maps and quantified elemental data. Automated mineralogy and associated detectors enable the characterization of target minerals such as gibbsite, kaolinite, and iron oxi-hydroxides. Example applications include:
勘探评估，提供矿石矿物学和形态的鉴定，以及矿石矿物质和煤矸石矿物质之间的纹理协会
Risk assessment for processing planning including minerals associated with reactive silica and identification of problematic minerals
通过量化饲料和尾部矿物质解放期间优化归属过程中的粉碎
Positive Materials Identification
Positive Materials Identification
Positive Material Identification (PMI) is a Non-destructive Testing (NDT) method critical in the mining industry. PMI is used to verify that supplied materials conform to the proper standards and specifications. The verification of alloy grade become a mission-critical safety consideration for mining, mineral processing, and smelting facilities that utilize high-temperature and high-pressure processes. Bruker’s NDT solutions include Optical Emission Spectroscopy (OES) and X-ray Fluorescence (XRF) for positive identification of nearly any alloy.
环境和修复
环境和修复
Bauxite mining exposes large areas to weathering and runoff, requiring special considerations for environmental management. Monitoring is important for the transport of heavy elements in surface water, the analysis of processing fluid discharge, and the assessment of contamination for closure and remediation. Bruker partners with operators to develop monitoring and remediation workflows that are efficient and accurate. Example applications include:
利用全反射XRF（TXRF）进行空气的麻烦测试水中的重点
Mapping contamination hot-spots with portable XRF
监测酸生成的可能性与自动矿物学
