Research

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 It has been mainly superseded in the past century by technology such as magnetic separation and flotation, but remains a very important process for base metal oxides (such as tin and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.

The Complex Orebodies Program is reaching the end of its second year of operation. This Presentation Day aims to provide researchers and other interested parties with an overview of the research programs underway, along with their outcomes and forward plans.

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.

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.

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.
