Our exploration projects are focused on gold and other strategic minerals like rare earth elements. RMML is the first private sector gold exploration company in India, having green field projects of gold in Gadag district of Karnataka. Few of them have been explored upto G1/ G2 level to set up gold mining and processing.
The use of analytical techniques is important and critical in all areas related to REE, such as basic fundamental research, exploration, mining, extraction, and metallurgical activities at different stages by different industries. At every stage of these activities, rock, ore, minerals, and other related materials have to be analyzed for their REE contents in terms of elemental, …

The world's largest producer of rare earths last month shipped 4,181 metric tons of the 17 minerals. China's Sept rare earth exports curbed by rising domestic demand, prices - MINING
The deposit contains ≥5.5% REO (rare earth oxides) and they are hosted in carbonatite dikes of about 10 cm wide (Wall and Mariano, 1996). LREE minerals such as bastnäsite, parisite, and synchysite have been reported from the Amba Dongar carbonatite complex, Gujarat (Doroshkevich et al., 2009).
In Saskatchewan, Canada, the Saskatchewan Research Council (SRC), a government-funded scientific research and development institution, built a $74 million rare earth minerals processing plant that became the first rare earth processing facility in North America to operate at a commercial scale this summer. The facility can produce 10 tonnes of neodymium …
American Rare Earths Inc. said Sunday that its rare earth minerals project near Wheatland could need $456 million to begin mine development and production, money that still needs to be raised by the tiny mining company valued at about one-fifth the initial project's size.
Rare earth mining can have hazardous impacts on the environment, including air pollution caused by the release of dust and gases into the atmosphere, water pollution from discharges that contain heavy metals and other pollutants, land degradation and soil erosion which leads to contaminated soil and habitat destruction. REEs also contain ...
The demand for rare earth elements for everyday technology and applications has initiated much research into the extraction and recovery of these rare earth elements. An otherwise unknown group of minerals, eudialyte is a zircon silicate consisting of rare earth oxides (REO), contained in a unique mineral structure and represented by a complex …
In another instance of the rush to mine rare earth minerals in the state, Rare Element Resources Ltd., a Canadian exploration company, is setting up shop on a large rare earth deposit in Upton, Wyoming, with a novel new mining process that promises to speed up rare earth processing. This is called the Bear Lodge Project.
Rare earth elements (REE), because of their coherent (geo)chemical properties, can be used as tracers of reactions and sources of materials within magmatic, hydrothermal and sedimentary systems. Over many decades, the improvements in the precision, accuracy and detection limits of analytical methods have been critical in establishing the role ...
The rare earth elements sector, pivotal for a range of high-tech and defense applications, confronts substantial challenges that threaten its sustainability and global supply …
A village was set up to support 15,000 miners working in the ruby mine near Ambatondrazaka, Madagascar. Photo: Pardieu et al. (2017). However, compared to many other industries such as agriculture, mining uses relatively small pockets of land, and the future of mining could move to using techniques that are arguably even less invasive on the …
