Smart SQUIDs sense underground ore bodies

By Nola Wilkinson As surface mineral deposits become ‘mined out’, increasingly mining companies are looking for ore bodies located deeper in the earth’s crust. Which poses a challenge – how to pinpoint the location of useful ores deep underground? Enter LANDTEM, a portable exploration tool developed by CSIRO. LANDTEM uses SQUIDs to tell the difference...

Supersonic magnesium

Did you know that magnesium is the lightest of all metals – about one-third lighter than aluminium? That it is non-toxic, non-magnetic, has high-impact strength, is castable and resistant to denting? All of which makes it a great fit for the global auto industry looking to find new ways to make cars lighter and more...

New sensor detects bombs on sea floor

We’ve developed a sensor to detect undetonated explosives on the sea floor, based on a technology used to find mineral deposits underground. The sensor was developed as part of a project with US Government agency, the Strategic Environmental Research and Development Program (SERDP) and US-based research organisation Sky Research. The method for finding undetonated underwater explosives...

Explorer of the year? It’s not Dora that’s for sure

Our Centre of Excellence for 3D Mineral Mapping was announced Australian Mining’s ‘Explorer of the Year’ last night. The team, led by Dr Tom Cudahy, developed the world’s first suite of maps that show the mineral composition of the surface of an entire continent. The maps are helping mining companies increase the efficiency and viability...

Nickel is worth more than a five cent coin

By Emily Lehmann Nickel seems to be the underdog of the metal world. While we have all heard of it, a casual ask-around among friends tells me that most people know little about its value and what it’s used for. Nickel is versatile because it mixes well with other metals to form alloys. It’s also...

Megatrends: do we really need more from less?

By Stefan Hajkowicz, CSIRO This article is part of The Conversation’s series on megatrends. What are the compelling economic, social, environmental, political and technological changes Australia must grapple with over the coming decades? This series is based on the release of the CSIRO Futures report, Our Future World 2012. Today, Stefan discusses food and water...

Worth the weight

For all of our readers sporting a wedding ring, here’s an interesting little tid bit you may not know – if it’s gold, it could weigh upwards of four tonnes – that could be how much ore, or rock, was dug out of the ground and processed to produce it. Now that the value of...

Australia creates world’s first continental-scale mineral maps

The new suite of mineral maps will enable mining companies to increase the efficiency and viability of their exploration efforts. The world-first maps were generated from a ten-year archive of raw Advanced Spaceborne Thermal Emission and Reflection (ASTER) data collected by NASA and the Japanese Government’s Japan Space Systems. CSIRO scientists have developed software that...
