From Drill to Mill: Can MWD data predict process performance?

15 November 2019 9:00am10:00am
Some production blast-hole drilling rigs are capable of measuring and storing various operational parameters while operating (Measuring While Drilling data-MWD). There are a number of examples from the literature where MWD data is used to predict rock properties such as lithology, strength and fractures. This study investigates the links between the MWD data acquired in laboratory and ore breakage parameters.

A Simple Recipe Guide to Gravity Concentration

8 November 2019 9:00am10:00am
Gravity processing is the oldest large-scale mineral concentrating technology. It has been mainly superseded in the past century by technology such as magnetic separation and flotation, but remains a very important process for base metal oxides (such as tin and tantalum) and precious metals recovery.

Artificial Intelligence and Machine Learning in mineral processing

1 November 2019 9:00am10:00am
Over the last decade there has been a strong move toward implementing Artificial Intelligence (AI) and in particular Machine Learning (ML) to improve the productivity of mining operations, enhance environmental and social performance and increase the health and safety of personnel. The mining industry is at the technological stage that we can develop a fully autonomous underground mine, integrate operational data for near-real-time decision making, promote the safety of people and control energy and water utilisation.

Iron Ore – Supply Chain and Minerals Processing

25 October 2019 9:00am10:00am
A brief overview of the iron ore market will be provided during this seminar, focusing on its nuances and the supply chain from pit to port in order to explain the driving factors behind the processing technology used for upgrading of low grade iron ore and magnetite iron ore to saleable products with the aim to identify areas for future improvement opportunities.
Anthony O'Sullivan

Seafloor Polymetallic Nodules – A clean solution to the Battery Metal Supply Gap

18 October 2019 9:00am10:00am
Every year, we extract 9 billion tonnes of metal ores and in the process, we create a 350billion tonne waste problem, destroy tropical habitats and carbon sinks, releasing toxic substances into the environment and emissions into the atmosphere. While metals do not have renewable substitutes, they can be recovered and recycled – that’s the good news. The bad news is, we currently do not have enough metal in the system to close the loop and we will need to inject a lot of virgin metal to provide for an additional 3 billion people this century.
Dr Kurt Aasly

Process mineralogy of non-metallic mineral deposits

4 October 2019 9:00am10:00am
Process mineralogy is typically related to detailed examinations of metallic ores and the relationship between mineralogical properties and mineral processing. However, process mineralogical techniques are widely used within other mineral sectors as well, such as on industrial minerals, although the main objectives of such investigations can be different.
Dr Marko Hilden

Energy efficiency and size energy relationships - revisiting Hukki’s curve

27 September 2019 9:00am10:00am
Trying to improve energy efficiency and modelling the energy of size reduction is one of the most important problems we face in comminution research. But regrettably, even the very definition of “energy efficiency” is elusive. The development of better grinding devices and circuits that use less of the world’s limited energy resources requires a clearer understanding of the relationship between energy and particle size.
Craig Vadeikis

The changing face of the mineral sands industry - Rare Earths

20 September 2019 9:00am10:00am
The Global Mineral Sands industry is predominantly focused on the production of titanium and zirconium bearing minerals such as ilmenite, rutile and zircon. However, in recent years there has been a shift in the attention of both explorers and producers to consider the minor rare earth bearing minerals of monazite and xenotime.
Pia Lois-Morales

Powers of Ten - Shifting scales of space and time for new perspectives in landscape change

23 August 2019 9:00am10:00am
This talk will begin with two keys premises: that landscape change is an intrinsic part of mining and industrial development; and that novel ways of understanding landscapes can open up new possibilities for their future.
Steven Micklethwaite

Drones, AI and the cloud - the new possible

16 August 2019 9:00am10:00am
This presentation focuses on research developments at Monash University where drones have been combined with high performance compute and computer vision techniques, in order to remotely sense or sample our planet.

The Language of Safety

9 August 2019 9:00am10:00am
When considering safety, especially in operating mines, the reporting of incidents and the language used to describe them really matters. Natural Language Processing can now be used to classify and detect new classifications of incidents and detect previously unseen combinations of hazards and behaviours, allowing for the development of meaningful and targeted safety intervention programs.
Emeritus Professor Ken Collerson

Cobalt and HREE Minerals Systems in the Eastern Mount Isa Block

26 July 2019 9:00am10:00am
A study of Co-rich samples from the Eastern Mount Isa Block was undertaken to constrain the IOCG mineral system and evaluate HREE prospectivity. Although these deposits are interpreted to have had a granitic source, the element association includes metals not normally concentrated in silicic melts e.g., Co, Ni, Sc and PGE's.
Pete Forakis

Project Derisking through metallurgical testing

14 June 2019 9:00am10:00am
Metallurgical testing is critical to a minerals project development. There are some key questions that need to be answered at each stage of a project from Scoping, to Prefeasibility and to Detailed feasibility and a key component is the process parameters evaluated during metallurgical testing.
Farhad Faramarzi

The Extended Drop Weight Testing Approach – What it reveals

7 June 2019 9:00am10:00am
For decades the minerals industry has been challenged by inherent variability of ore deposits. Quantifying this characteristic of orebodies and estimating its impact on the process performance is becoming increasingly important because the mining industry needs to extract resources with lower grades and more complexities.
Dr Kieren Moffat

A data driven approach to social license

31 May 2019 9:00am10:00am
A decade of research on the nature of relationships between communities and the mining companies that work alongside them, has demonstrated that community acceptance, or social licence, depends on deeper trust in their relationships
Trevor Hadley

Real-time process improvement through advanced instrumentation and control strategies

24 May 2019 9:00am10:00am
With the decline of in-house expertise, in both the research organisations and end users of technology, Clarity bridges the implementation gap of new technologies and industry solutions.
Daniel Brooks

Understanding the margins - Application of energy at the EHM Concentrator

17 May 2019 9:00am10:00am
Utilisation of a processing asset extends beyond the number of hours it runs for. When mines start to approach the end of their life, significant redundant capacity opens up in the mines processing assets. Is this capacity really redundant or can we re-think our approach to keep them delivering value at the design rate?
Professor Rick Valenta

Complex Orebodies - the story so far

10 May 2019 9:00am10:00am
The Complex Orebodies program has now been going for 15 months. The program has the aim of identifying the challenges and solutions related to responsible unlocking of Complex Orebodies - orebodies which are currently inaccessible due to complexities across the range of Social, Environmental, Governance and Technical areas. This presentation will provide an update on the overall program, its performance against the original objectives, and future plans.
Professor Malcolm Powell

Applying Integrated Process Knowledge to viable recovery of complex orebodies

3 May 2019 9:00am10:00am
The seminar is linked to the risk factors preventing the utilisation of 75% of the world's large known copper resources.  A picture will be painted of how being able to link the processing route to the knowledge of primary rock properties can enable modelling, and therefore risk reduction and potential acceptance by the industry, of dramatically different approaches to the mining process.  Linking technical understanding to mapping routes that can dramatically change social benefit, environmental impact, water and energy usage, tailing and waste management, and long-term society benefit from mineral resources.
James Vaughan

Processing Iron Oxide Copper Gold Uranium Ore

12 April 2019 9:00am10:00am
Iron oxide copper gold uranium ore is an important source of metal for Australia. Processing of IOCG-U ore is complex due to sequential separations resulting in multiple products and the need to carefully consider the deportment of radioactive elements. ‘For the process to be effective, geologists mineral processors pyro and hydro-metallurgists must work together.’

Pyrite types and their effect on flotation electrochemistry

5 April 2019 9:00am10:00am
Pyrite is one of the most important minerals in the beneficiation of gold, platinum group metals, and base metals such as copper. However, “pyrite, is not pyrite, is not pyrite”. Many types of pyrite exist, with a high level of variability between them. Identifying different pyrite types within ores and understanding their properties has enormous benefits towards improving the flotation process.
Dr Chris Greet

The parable of the blind man and the elephant!

29 March 2019 9:00am10:00am
The objective of this seminar is to impart how the composition of the grinding media can influence particle hydrophobicity and the flotation response, and secondly explore how measurement of pulp chemical parameters can be used to improve flotation outcomes.
Brett Garland

22 March 2019 9:00am10:00am
Do not wait for a disaster to improve the controls to prevent it.
Dr Roger Higgins

Planning for Positive Post-Mine Legacies

15 March 2019 9:00am10:00am
The best examples of mine planning and closure work are transforming the notion of ‘the-life-of-the-mine”, so that closure is not simply the end of the mine, but a point in time in a much larger process of community development, environmental health, and economic transformation.
Neil McIntyre

Mining and regional water security: Linking site operations to regional water problems and solutions

8 March 2019 9:00am10:00am
Parts of the mining sector are quickly recognising the risks and opportunities associated with their role in regional water systems, and are endeavouring to be better “water stewards”. Advances in unit process technology and efficient on-site operations underpin this effort, but increasing attention is being directed at the wider outside-the-fence and beyond-closure challenges. This seminar presents three diverse examples of research supporting the sector’s endeavours.

Comminution Energy Efficiency – Three horizons of technological innovation

1 March 2019 9:00am10:00am
On his final day before transition to the world of engineering consultants, Grant will present a keynote he recently gave in Brazil. This presentation represents the culmination of his research over the years at the JKMRC from the Comminution Energy Curves, through various case studies and the integration of comminution, classification and flotation.
