This course integrates geology, mineral liberation and comminution (crushing and grinding) circuit design prior to mineral separation. It provides an important foundation to the study of mineral extraction techniques.
METL3219 is a 2 unit course designed to integrate geology, mineralogy, mineral liberation and comminution circuit design. The course deals with the processes responsible for the formation of ore deposits and the characteristic features of mineralised environments and will equip you with relevant skills to extract the maximum value from ore characterisation data commonly used in process design and diagnostics. It provides an important foundation to the study of mineral processing techniques and includes a solid core of learning materials and activities that provide the basis for skills development and articulation of these skills into practice. This course is compulsory for the Chemical and Metallurgical Engineering Program.

Aims and outcomes
The aims of the course are to:
(i) Develop an understanding of ore characteristics and how valuable minerals are liberated from ores for recovery through the process of rock breakage - comminution.
ﾠ (ii) Provide an understanding of the following key concepts:
ﾠ • The physical and chemical properties of minerals are determined by the bonding of species within these compounds and the respective crystal structures.
• The degree of liberation that must be achieved through ore breakage is a function of the subsequent separation processes that are to be employed.
• Rock and ore breakage characteristics are dependent on the comminution technology employed and the ore characteristics.
• The ore characteristics and degree of liberation required for separation can be predicted or assessed using quantitative process mineralogy techniques.
• Overall process optimization from orebody to product is achieved through assessment and appropriate integration of all operations in the overall process.
Learning outcomes
After successfully completing this course you should be able to:
LO1.
Understand and explain the origins of orebodies and their occurrence, mineralogy and physical form and be able to recognize the major ore types and gangue minerals.
LO2.
Understand and interpret the relationships between ore properties, ore microstructure textures, mineral liberation and comminution.
LO3.
Undertake calculations related to analysis of comminution circuits with confidence and specify appropriate equipment for a given comminution requirement.
LO4.
Understand basic liberation theory, interpret liberation data and undertake methods for measurement of liberation.
LO5.
Communicate with geologists, mineralogists and metallurgists and have sufficient knowledge and vocabulary to access and interpret the ore geology, mineralogy and comminution literature at an intermediate level.
LO6.
Identify the social impact and sustainability issues surrounding the energy intensive comminution process.
LO7.
Improve teamwork skills through practice, reflection and feedback.

Task description
Students will be provided with a series of processing scenarios and associated data and are required to use the information provided to analyse data and interpret process performance. Students are required to submit the analysis of the process scenarios via Blackboard.
This is an individual assessment.
Artificial Intelligence (AI) and Machine Translation (MT) are emerging tools that may support students in completing this assessment task. Students may appropriately use AI and/or MT in completing this assessment task. Students must clearly reference any use of AI or MT in each instance. A failure to reference AI use may constitute student misconduct under the Student Code of Conduct.
Submission guidelines
Submission via Blackboard.
Deferral or extension
You may be able to apply for an extension.
The maximum extension allowed is 7 days. Extensions are given in multiples of 24 hours.
The 7-day maximum extension is set to ensure timely feedback to students within 1 – 2 weeks. Any long extension will make it difficult for the teaching team to post solutions to the Blackboard in a timely manner.
Late submission
A penalty of 10% of the maximum possible mark will be deducted per 24 hours from time submission is due for up to 7 days. After 7 days, you will receive a mark of 0.
