Bauxite Mining and Aluminum Processing

Bauxite (aluminum hydroxides, gibbsite, boehmite and diaspore) is the primary source for aluminum (Al). Explore how Bruker’s analytical instrumentation can improve efficiency by accurately determine concentration of aluminum, grade, and identification of penalty elements.

介绍

布鲁克's Analytical Technology Helps to Meet Production Targets, Ensures Quality and Saves Costs in the Aluminum Industries

铝土矿是铝的主要来源。铝土矿是一种以吉布斯特岩,铜矿或炎热形式形式的水合氧化铝,通过表面风化和直接化学沉淀形成。表面过程引入了矿石和杂质组成的复杂性和多样性,在设计勘探,等级控制和过程控制工作流程时,需要仔细考虑分析技术。布鲁克的分析工具使铝土矿开采的所有阶段都从探索到修复。

XRF for all Phases of the Bauxite to Aluminum Value Chain

X-ray Fluorescence (XRF) XRF provides chemical analysis. Uses of XRF during bauxite mining and exploration include:

  • 勘探映射,核心扫描和预期存款的识别

  • Delineation of the extent of resource and cutoff grade during mine assessment

  • 级控制在中央labora矿业tories and on-site

  • Process control for alumina processing and electrolysis, including analysis of additives to electrolysis systems such as cryolite, CaF2, AlF3, MgF2 or LiF

  • For metals characterization and final product QA/QC of cast aluminum and its alloys, refractory materials, raw material for anode production, and the anode coals

批量矿物分析

批量矿物分析

XRD directly measures the mineralogy. Knowing about mineral impurities such as clay or iron oxide in bauxite is the key to beneficiation in the alumina refinery and thus reduces residues. In the smelter XRD measures the mineralogy of the congealed electrolyte. Control parameters are derived that are essential for managing the operation of the smelter cells. Furthermore, the anode quality is monitored by XRD.

微分析和自动矿物学

微分析和自动矿物学

自动矿物学将扫描电子显微镜(SEM)的成像功率与能量色散光谱法(EDS)结合在一起,以生成矿物图和量化元素数据。自动化的矿物学和相关检测器能够表征诸如gibbsite,高岭石和氧化铁氧化铁等目标矿物质。示例应用程序包括:

  • Exploration assessments providing identification of ore mineralogy and morphology as well as textural associations between ore minerals and gangue minerals

  • 用于处理计划的风险评估,包括与反应性二氧化硅相关的矿物和有问题的矿物

  • Optimization of comminution during the beneficiation process by quantifying mineral liberation in feeds and tails

阳性材料识别(PMI)是采矿业至关重要的一种非破坏性测试(NDT)方法。PMI用于验证提供的材料符合适当的标准和规格。bob综合游戏合金级的验证成为采矿,矿产加工和使用高温和高压工艺的矿物质处理和冶炼设施的关键安全考虑因素。Bruker的NDT溶液包括光发射光谱(OES)和X射线荧光(XRF),用于阳性几乎任何合金。

Environmental and Remediation

Environmental and Remediation

铝土矿开采暴露了大面积的风化和径流,需要特别考虑环境管理。监测对于地表水中的重元素的运输,加工流体排放的分析以及污染的封闭和修复评估很重要。Bruker与操作员合作,开发有效和准确的监视和补救工作流程。示例应用程序包括:

  • Utilizing Total Reflection XRF (TXRF) for hassle-free testing of heavy elements in water

  • 用便携式XRF绘制污染热点

  • Monitoring acid generation possibilities with automated mineralogy
