A contribution to the key question related to tailings - When does a soil behave like a soil and how can we observe that?

7 August 2020 9:00am10:00am
The presentation deals with the question from which condition onwards soil starts to show soil-like properties and how they relate to potential failure mechanisms for Tailings Storage Facilities. Special attention will be given to an emerging monitoring technology based on the electromagnetic measurement method dielectric spectroscopy.

The Geopolitics of Metal Supply Security – Mining, the Circular Economy and Beyond

31 July 2020 9:00am10:00am
The current global tensions between China and the West have the potential for leading to major disruptions in metal supply. This presentation will consider the latest data on supply security based on recent research conducted on resource efficiency, recycling, remanufacturing and frontier sources of metals. The presentation will also explore what role technical mineral processing research can play in relieving some of the stresses created by such geopolitics.

GSQ’s New Economy Minerals Initiative: geoscience for a technology-driven future

12 June 2020 9:00am10:00am
‘New economy minerals’ is an umbrella term for a range of metals and mineral elements used in many emerging technologies including electric vehicles, renewable energy products, low-emission power sources, consumer devices, and products for the medical, defence and scientific research sectors. As Queensland is potentially rich in these minerals, it is well-placed to meet rapidly expanding domestic and international demand. This presentation will introduce the importance of New Economy minerals to Queensland, and the steps being taken by Government to support and boost exploration for these commodities in the state.

Factors affecting high voltage pulse rock breakage and pre-concentration

5 June 2020 9:00am10:00am
Mineral extraction is increasingly moving towards low grade ore bodies with increased comminution energy requirements. Previous work at the JKMRC has established the potential of pre-concentration with HVP technology as a solution to these increased energy demands, however, a detailed understanding of the factors that affect pre-concentration performance does not currently exist. This study examines machine-related factors and their impact on rock breakage and pre-concentration performance.
Professor Simon Michaux

How to Set Up and Develop a Geometallurgical Program

29 May 2020 9:00am10:00am
A successful geomet project requires planning and experimental design. Consistent and methodical test work allows for amazing data analysis. The magic is in the data relationship between the various technical areas. This seminar will discuss the design and implementation of a geometallurgical program.

Webinar: Grade Control in The Time of Coronavirus

22 May 2020 9:00am10:00am
There is always potential to innovate and improve a gadget or process, no matter how mature the technology may seem to be.
John Jackson

Webinar: Enabling short interval control using spatial dense geoscience information beyond grade

15 May 2020 9:00am10:00am
Improvements in productivity, efficiency and safety always rate in the top 10 trends, risk or opportunities from mining industry surveys. One area of focus to achieve productivity improvements over the past few years has been through the application of technology, automation and data analytics primarily focussed on existing mining equipment. This presentation will look at the current development of an automated system to enable precision mining by providing spatially dense knowledge of the rock, beyond grade, for short interval control – improving blast outcomes, material control and downstream processes.
Daniel Hastings

Webinar: The importance of cashflow grade modelling in strategic mine planning

8 May 2020 9:00am10:00am
Cashflow grade modelling is a major component of the strategic planning process. It combines geology, metallurgy, mine planning, marketing, environment, finance and a number of other aspects of an operation or potential operation to provide information crucial to the strategic planning process.

Webinar: Mobilising METS – creating cooperative pathways to customer-centric solutions

1 May 2020 9:00am10:00am
There is great opportunity to expand the depth and breadth of relationships between the METS and Research communities. Global pressures in mining present both opportunity and threat to METS companies looking to grow. The pace of change is fast, challenges are becoming more complex and competition is fierce. New partnership models provide the potential for quicker pathways to commercialisation for research and vital new innovation opportunities for METS companies.
Professor Gordon Southam

Webinar: Bacteria-mineral interactions important to mining

24 April 2020 9:00am10:00am
This webinar aims to convey the catalytic power and diversity of the microbial biosphere in transforming Earth surface environments; highlighting the broader, as yet unrealised potential to develop biotechnological processes for the mining industry.
Professor Rick Valenta

Webinar: Complex Orebodies Program Update

17 April 2020 9:00am10:00am
The Complex Orebodies Program is now into its third year of operation. This presentation will cover progress to date on the program, showcasing a range of the exciting projects, outputs, impacts and collaborations which have resulted so far.
Professor Anna Littleboy

Webinar: A Cooperative Research Centre for Transformations in Mining Economies: So what?

3 April 2020 9:00am10:00am
In March 2020 the Federal Government announced a new $130 million Cooperative Research Centre on Transformations in Mining Economies (CRC TiME). The University of Queensland, through the Sustainable Minerals Institute, led the development of this cooperative research centre in partnership with The University of Western Australia.
This presentation will outline: the basic components of CRC TiME; the game changing value proposition which positions the mining industry as an agent of regional development; and the unique partnership that has drawn in mining companies, technology and service suppliers, state and local governments and groups representative of regional and community interests.

Webinar: On-belt bulk analysis - latest applications and development

27 March 2020 9:00am10:00am
Real time measurement is essential for improved plant control. Bulk ore sorting is automated grade control between the mine and mill and sensing data can be used concurrently for multiple purposes (ore blending, diversion, reconciliation, metal accounting, feed forward control, etc).

Webinar: Climate change mitigation in mining

20 March 2020 9:00am10:00am
Climate change accountability plays a critical role in ensuring the security of the future of minerals supply. Mining has an important position in enabling our modern lifestyle and the development of infrastructure for green technologies; and, therefore, it is important to acknowledge and point out the risk of climate change on mining infrastructure. A comprehensive carbon accounting framework, that takes into consideration all mitigation opportunities, is required to implement climate change mitigation strategies within mining supply chain.

Investigating the effect of process water salinity on the flotation performance – ArcelorMittal Kryvyi Rih case study

6 March 2020 9:00am10:00am
Process water can potentially be reused in flotation, particularly in the reverse cationic flotation of magnetite concentrates – the Kryvyi Rih (Ukraine) case study concludes that unwanted silica content reporting to the magnetite concentrate during reverse flotation can significantly be restricted following the proposed methodology for reusing process water.
