The Australian copper industry has developed a new range of tubes to handle large scale refrigeration. The addition of transcritical CO2 refrigerant systems for large scale refrigeration applications, initially for freezers in retail food outlets, requires tubes of higher strength than previously available in the market. The previous range of tubes catered for pressure ratings […]
Can Copper Corrode?
Generally no-even after centuries under soil-but there are some underground situations where it can, including: abnormally aggressive soils localized and long-line-type concentration cells created by differences in soil composition the action of stray direct currents (DC) flowing in the ground faulty design and workmanship certain conditions created by alternating currents (AC) thermogaivanic effects galvanic action […]
Copper’s Green Agenda
There seems to be a spirit of innovation happening around copper these days. Both in terms of exploration and production. That was the theme of South Australia’s Copper To The World conference last year and I expect it’ll be much the same for the next one in June. We had some interesting projects out of […]
Mapping Copper Risks
New study maps risks the mining industry must overcome to unlock new copper reserves. Australian researchers have identified a matrix of risks including environmental, social or governance that could impede future copper discoveries. University of Queensland geologist Professor Rick Valenta said copper would be crucial in a renewable-powered future, but global supplies were far from […]
OZ Minerals $1B Expansion
South Australian copper miner OZ Minerals plans to spend another billion dollars on expanding its Carrapateena underground mine. The investment is designed to help the company more than double copper production from the still under construction mine from 2026. The miner said it would progress its Carrapateena Block Cave Expansion to pre-feasibility and the Carrapateena […]
OZ Minerals A$1M Explorers Challenge
OZ Minerals and energy and resources open innovation platform, Unearthed, are launching the A$1M Explorer Challenge. This unique, online crowdsourcing competition calls for geologists and data scientists from across the globe to develop ground-breaking approaches to discover new exploration targets at a site near OZ Minerals’ Prominent Hill copper- gold mine in South Australia. With […]
Teen Inventor Makes History
Macinley Butson may be young but her “copper armour’ to improve breast cancer treatment is just one of her inventions. Macinley Butson was still in school when she came up with the idea of a copper armour to help protect women undergoing cancer radiotherapy. Macinley found copper ‘scale maille’, a type of medieval armour, is […]
South Australia’s 2nd Copper Coming
BHP Group has unearthed a major new copper find in South Australia and that could put the state on a path to a “copper renaissance”. BHP has revealed a large iron oxide copper gold (IOCG) deposit on the Stuart Shelf, 65 kilometres southeast of Olympic Dam-already the world’s third largest copper equivalent deposit. In an […]
Remote Mines, City Riches?
Mines may be out of sight for most of us, but they’re having a direct impact on all our lives. Well that’s the take out from new figures showing the Queensland resources sector delivered $62.9B to the State’s economy in 2017-18. Up 14% on the previous year. Queensland Minerals Council summed it up “Brisbane is […]
Indian Copper Demand On The Rise
India’s copper consumption is set to more than double over next decade says expert. The prediction comes from J.C. Laddha, Chief Executive Officer of Birla Copper, one of the country’s top copper smelters. Speaking at the Asia Copper Conference in Shanghai in November, Mr Laddha was quoted in the media as saying the rising demand […]
Finding Copper In ‘Deep Australia’
A new ‘downward-looking telescope’ could unlock Australia’s hidden mineral wealth. The Australian Academy of Science is proposing the development of the cutting edge telescope with the ability to peer at least 300 kms beneath the Earth’s surface. The proposal is one of several in a 10-year plan for Australian Geoscience just launched by the Academy’s National […]
Copper’s “Belt & Road” Boom
BHP Billiton says China’s global infrastructure initiative “Belt & Road” will have a bigger impact on copper demand than first predicted. Often described as a 21st century “silk road, it is made up of a “belt” of overland corridors and a maritime “road” of shipping lanes. In the latest “episode” of BHP’s blog on the […]
