NdPr oxide, Sloustcher says, is the "key commodity that drives economic value" in the rare-earth industry, and MP Materials believes it is "a low-cost NdPr producer globally."
China's ionic rare earth ore is a unique rare earth mineral resource in the world, being rich in medium and heavy REEs, which are urgently needed in various high-technology applications and for new materials. The contents of medium and heavy REEs are 4–20 times higher than those of similar industrial minerals abroad.
Recovering REEs from coal-related materials has several advantages over commercial rare earth ores: (1) coal-related materials contain more heavy and critical …
Neodymium (Nd) and praseodymium (Pr) are expected to generate 90% of Ngualla's future revenue. Deliverability and operability. Completion of the BFS by Peak Resources' team of rare earth industry experts in conjunction with global engineering firm Amec Foster Wheeler, including the extensive pilot planting of Ngualla ore, has …
Barrick put the open pit mine on care and maintenance in 2019, but production continued from the heap leach. Boroo expects to recover approximately 100,000 oz. of gold inventory by 2023.
The microbial community and functional flora in rare earth mining areas are correlated, but the characteristics and metabolic pathways of pollutant in such mining areas are still poorly known. The heavy metals, rare earth elements, and microorganisms present after mining of rare earth mine sites were analyzed. After mining, all sampling sites …
This approach is risky; extraction from unconventional sources can cost more than mining, given the low concentrations of rare earth elements and the greater initial concentration of toxic ...
CEO Andrew Mackenzie announced the firm would cut capital and exploration expenditure to $9 billion in the 2016 financial year from $12.6 billion in 2015.
The mining of ion-adsorption rare earth ores involves three leaching processes: pool, heap, and in-situ leaching. Leaching agents and methods have been continuously developed and improved. Such rare earth ores cannot be obtained by conventional separation methods such as gravity separation, magnetic separation and …
BHP Billiton has announced plans to cut capital spending and operating costs for iron ore, following the company's demerger of South 32.The strategy aims to make BHP the lowest-cost iron ore mining company in the world. "The iron ore and metallurgical coal markets are currently well supplied and we do not expect to invest …
FL has signed an EPS contract worth more than EUR 160m with the Russian marine export terminal owner OTEKO-Portservice LLC for the engineering, supply and supervision of material handling ...
Coal fly ashes and stormwater sediments are the most promising REE dilute sources. Metals, including rare earth elements (REE), are the cornerstone of our current …
This article explores how sustainable plant improvements in crushing and screening can translate into productivity, cost savings and profitability. Careful selection of crusher spares and wears
The Department of Energy has set 300 ppm as the minimum concentration for rare earth mining to be potentially economically viable.
He, Z. et al. Kinetics of column leaching of rare earth and aluminum from weathered crust elution-deposited rare earth ore with ammonium salt solutions. Hydrometallurgy 163, 33–39 (2016).
China set a quota for the first batch of rare-earth mining in 2023 at 120,000 tons in March, up by about 20% compared with last year while its exports of rare earths in June jumped to the highest ...
The chemical reaction of ion-adsorption-type rare earth ore during the in situ leaching process is accompanied by ion migration and charge movement, making the leaching process electrochemical in nature. The chemical reaction rate plays an important role in the leaching rate of rare earth elements. In this work, electrochemical impedance …
Red Metal Ltd's "metallurgy-first" approach to defining the potential of its unusual rare earths discovery in Queensland has paid early dividends, with tests showing extraction levels of up to 90 per cent on two key elements. Its Sybella project represents a potentially new deposit style for Australia – and possibly the world – with its rare earths …
To demonstrate this, we used a sample of rare-earth element carbonatite ore for correlative microscopy and co-location analysis.
One of the key advantages of the new crusher is its flat and compact design with integrated screen. It is 20 to 50 percent lower than conventional primary crushers.

For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.
