DESCRIPTION - summary of the module content

The module gives graduates from a range of disciplines the opportunity to study the fundamentals of process mineralogy and geometallurgy. The module introduces you to the main analytical techniques used to analyse rock and minerals and how these can be integrated to support and enhance physical test work. It also gives you practical experience of testwork guided by mineralogy and will help you to devise analytical strategies to evaluate results during processing and in academic studies.

The module will also introduce the key concepts of geometallurgy which is an over-arching subject area encompassing process mineralogy and geo statistics.

The module contains a group project and is very helpful if you do analytical work done as part of the MSc research project.

If you take this module, you should have a basic understanding of physical chemistry and would benefit from a basic knowledge of mineralogy. Support and guidance in self-study to improve understanding in these areas can be provided. This module is suitable for non-specialist students and those on interdisciplinary pathways.

 

AIMS - intentions of the module

This module is designed to give you practical experience and a theoretical understanding of process mineralogy by introducing you to the main analytical methods applied in minerals processing and how these can be best utilised to support and enhance physical test work. The module will give you an understanding of the principles of geometallurgy, its links to process mineralogy and its importance for reducing risk in minerals processing. Innovations in geometallurgy and process mineralogy will be discussed and critically analysed.

It also aims to enable choice of the most appropriate analytical methods and strategies for routine analysis and for research. Furthermore, it teaches you best practice in sampling design, data handling and quality control.

 

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

SYLLABUS PLAN - summary of the structure and academic content of the module

Process mineralogy topics

1. Consideration of the characteristics of mineral and rock samples and other materials relevant to minerals processing;

2. Analytical techniques including sampling and processing of results for:

  • Whole sample chemical techniques: EDS and WDS X-ray fluorescence, inductively coupled plasma mass spectrometry, atomic absorption spectroscopy, inductively coupled plasma optical emission spectrometry;
  • Whole sample mineralogical techniques: X-ray diffraction plus very brief introduction to transmission electron microscopy, synchrotron techniques;
  • Spatially-resolved techniques: SEM, electron beam microanalysis;
  • Quantitative spatially-resolved techniques: QEMSCAN, MLA;
  • Other techniques: Raman spectroscopy, laser induced breakdown spectroscopy.

3. Practical project work integrating quantitative mineralogical analysis to inform processing, adopting a process mineralogical approach.

 

Geometallurgy topics

1. Introduction to geometallurgy: overview of the role of geometallurgy in the mineral extraction industry. Including the general principles and techniques associated with geometallurgy and the links to process mineralogy.

2. Geostatistical modelling: overview of geostatistical techniques used to model the spatial distribution of key processing properties in a geometallurgical framework.

3. Case studies: Examples of the application of geometallurgical modelling to mines and mineral deposits.

4. Discussion of the latest innovations and trends in geometallurgy, including critical interaction with relevant research menuscripts and conference proceedings.

 

Laboratory exercises

1. Students will undertake a process mineralogy investigation, including designing a test programme, interpreting analytical data and completing experiments.

 

Health and safety engagement

1. The health and safety implications related to comminution, physical separation will be covered. This will include discussion of safe use of devices which produce ionising radiation, the dangers of working with different mineral types, controlling and handling of chemicals, safety aspects of industrial processes and safe lab practices.
