Minerals: Mining and Mineral Processing

过程矿物学

Process mineralogy involves the analysis of relationships between ore and gangue (accessory) minerals to optimize the recovery of target elements. Bruker’s solutions for quantitative mineralogy provide critical information to process engineers and metallurgists throughout the processing workflow.

Introduction

过程矿物学

工艺矿物学是矿石中矿物质的表征,以优化从废岩或脉管中回收有价值的矿物的过程。布鲁克(Bruker)具有一系列分析解决方案,可以提供矿物学信息以优化恢复。

Ore Characterization

Ore Characterization

More and more emphasis is placed on understanding the ore body in as much detail as possible before mining commences. This approach is not only driven by a need to reduce risk and cost, but by the fact that ore bodies are becoming increasingly lower-grade and complex. Mineralogy is crucial in understanding the variability of the ore body, and also to highlight problematic minerals that can impact on grinding, flotation and/or leaching. Hazardous mineral species need to be identified to mitigate any problems during the remediation stage.

Detailed mineralogical information such as texture (grain size and grain boundary relationships) is important to understand how difficult it would be to separate valuable minerals from gangue and determine the viability of a project. Bruker offers solutions to perform ore characterization from drill core samples to pilot plant feed products.

Plant Design

Plant Design

为了有效设计植物,有必要了解饲料的矿物质学。Bruker提供的解决方案可以提供从基本到高级水平的矿物学信息。散装矿物学可以指示硬度。某些矿物质(例如粘土或碳酸盐)的存在可能表明未来的浮选或浸出困难。

Add to this characteristics about the textural relationship (size, grain boundaries) of the valuable mineral with gangue and recommendations on grinding can be deducted. Further detailed quantitative analysis on selected mineral phases can highlight the presence of elements that could be problematic due to penalty elements or hazardous components such as arsenic and mercury.

Plant Optimization

Plant Optimization

详细的矿物学是确保proc的关键essing plant maintains optimum efficiency as the plant feed or flow sheet changes. Bruker has the solutions to not only determine the mineralogy, but the ability to track the degree of liberation of target minerals in the feed and products. At the same time data, such as the grain size and association of any mineral, can be calculated on statistically sound data. Such detailed information is useful to understand deleterious minerals and limit the occurrence of penalty elements in the concentrate.

尾矿特征

尾矿特征

尽管尾矿被视为废料,但矿物学表征同样重要。尾矿特性可能会有很大的变化,不仅受矿石矿物学变化的影响,而且还受到用于提取有价值矿物的物理和化学过程的影响。

Detailed knowledge of the tailings characteristics is vital to ensure that valuable materials are not unnecessary loss, and equally important to determine the behavior of the tailings once stockpiled. Environmental standards are becoming more demanding to ensure that tailings should not cause harm to people or the environment.
