Wärtsilä Energy Business, which leads the transition to a 100% renewable future, has researched hydrogen as a fuel for two decades. It said it is developing its combustion gas engines to run on 100% hydrogen fuel and has already tested its engines to run on a 60:40 mix of hydrogen and natural gas according to International Read More
Oz Minerals will use an optimized mix of solar, wind, battery and diesel power for its proposed copper-nickel project in West Musgrave, Australia, according to Mining Technology. Oz Minerals and Cassini Resources own the project in the ratio of 70:30 respectively. According to its pre-feasibility report released Wednesday, the mine will produce 28,000 tonnes of copper Read More
Almost a dozen new renewable energy projects were announced in 2019. Many others were already under development, and more are under negotiation or could be announced soon. Miners finally bit the renewable energy bullet this year as its economics and technical feasibility, particularly at remote locations, became too compelling to ignore. Key advantages were lower cost, Read More
Rio Tinto announced an A$1 billion investment at its Western Turner Syncline Phase 2 (WTS2) iron ore mine in the Pilbara, Western Australia. The amount includes the construction of a 13 km long conveyor system that will help lower greenhouse gas emissions from the mine by 3.5% compared to road haulage. Giles Parkinson says in an Read More
Gold mining companies run power-hungry operations, with a substantial carbon footprint. Last year, for every tonne of gold produced, greenhouse gas emissions released were 32,689 tonnes, according to a report from the World Gold Council. However, gold miners are resorting to new and innovative means to reduce reliance on fossil fuels and abate carbon footprints, according Read More
Escondida, BHP’s massive copper mine in Chile, will switch completely to renewable sources of energy, according to the company’s chief external affairs officer Geoff Healy. The 1.2 million tonne Escondida operation currently relies on gas for its energy requirement. One of the world’s largest copper mines, it produces approximately 20% of the global copper concentrate supply. Read More
Oz Minerals, the Australian mining giant, is harnessing wind and solar power for its West Musgrave mine to reduce the high costs from fossil fuels. West Musgrave is the largest unexplored nickel-copper deposit in Australia. Power accounts for 40% of the mine's processing costs. "Large-scale solar photovoltaic and wind solutions are currently economically viable and technically Read More
A mine considering introducing hybrid renewable energy in tandem with gas or diesel generation, should look beyond technology costs, to time-based factors of remaining mine life and the duration of the current power purchase agreement (PPA). These criteria are more compelling than anticipated future savings. Amiram Roth-Deblon, head of Juwi global initiatives explained at a webinar, Read More
Renewable energy and mining have conflicting priorities in Australia, the national Minerals Institute reports. Over 50% of Australia’s export income comes from coal, iron ore, and liquefied natural gas. BHP is reconsidering membership of Minerals Council of Australia, World Coal Association, and US Chamber of Commerce owing to pressure to reduce emissions. Yet it could save Read More
