铝土矿开采和铝加工
Introduction
布鲁克的分析技术有助于实现生产目标，确保质量并节省铝业的成本
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。了解铝土矿中的粘土或氧化铁等矿物质杂质是氧化铝炼油厂的收益的关键，从而减少了残基。在冶炼厂中，XRD测量了凝结电解质的矿物学。得出控制参数，这对于管理冶炼厂单元的操作至关重要。此外，阳极质量由XRD监视。
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:
探索评估提供鉴定矿石矿物学和形态的识别以及矿石矿物与脉管矿物质之间的质地关联
Risk assessment for processing planning including minerals associated with reactive silica and identification of problematic minerals
通过量化饲料和尾巴中的矿物质解放，对粉丝过程中的洞察力进行优化
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.
环境和补救
环境和补救
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:
利用总反射XRF（TXRF）进行水中重元素的无麻烦测试
Mapping contamination hot-spots with portable XRF
用自动矿物学监测酸的产生可能性
