Five Steps for Solving the Rare-Earth Metals Shortage BCG

The rare-earth industry can be divided into three stages: upstream, or the mining of elements; midstream, the processing of elements into separate oxides; and Indeed, in August 2018, Lynas announced a 70% increase in the mine’s mineral resources and a 60% increase in ore reserves. This pushed the total life of the mine beyond 25 years, making this a reliable long-term project. The mine’s concentrator can produce around 240,000 tonnes of ore, including around 26,500 tonnes of rare earth Australia’s latest rare earth mines Mining Technology

Construction begins on Lynas’ rare earths refinery in Western

In the second piece of rare earths news this month, construction has begun on Lynas Rare Earths’ new processing facility in Kalgoorlie. The refined products are used in batteries and other renewable technology, with Lynas moving the processing it currently does in Malaysia onshore for the first time. April 26, 2022 Bella Peacock. Credit: Iluka Resources. In April 2022, Iluka Resources, an Australian-based resources company, committed to building the country’s first rare earths refinery, Eneabba, after lining up around $834m (A$1.25bn) in loans from the government as part of the state’s plans to diversify critical minerals supply away from China.Developing rare earths refineries in Australia Mining Technology

Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits.Yet interest in rare earths is not exclusively a new phenomenon, and this is perhaps best demonstrated by Lynas Rare Earth’s Mount Weld mine in Western Australia. The mine began production in 2007, decades earlier than other miners were even submitting licencing applications for other projects, and the mine has undergone a number of “Vision becoming reality”: the history of Lynas’s Mount Weld mine

Critical and rare: the minerals Australia can supply to the world

Interest has piqued since the 2010s, with more rare-earth prospecting, but essentially Australia, despite being the fourth-largest producer of rare-earths in the world, still sits on a vast and untapped quantity of these materials. “The statistics are that Australia might have something like 20% of the world’s supply of rare earthsABUNDANT RESERVES: According to a 2009 survey by US government geologists, there are 31m tonnes of rare earth resources in Mongolia, which is equal to 16.8% of known reserves worldwide and makes Mongolia the second-biggest source globally after China. Exploration efforts are ongoing, however, and more minerals are expected to be found.- Mongolia 2012 Oxford Business Group

Rare Earth Elements: Overview of Mining, Mineralogy, Uses

Rare earths are used in the renewable energy technologies such as wind turbines, batteries, catalysts and electric cars. Current mining, processing and sustainability aspects have been described in this paper. Rare earth availability is undergoing a temporary decline due mainly to quotas being imposed by the Chinese Mining the UK. The days of deep coal mining may be largely gone for the UK, but small-scale, varied mines are ensuring the industry’s survival. In this interactive map, we spotlight some of these sustaining projects, including lithium mining in Cornwall, tin mining in Devon and gold mining in the Highlands.
