Earth's plants evolved some 700 million years ago. That's well before the first animals appeared on the scene (about 550 million years ago). Over such a long and rich history, plants have had to adapt. They have dealt with extinction events, ice ages, continents breaking up, and environmental changes caused by humans.

This study investigates the geochemical characteristics of rare earth elements and yttrium (REE + Y) in the neutral mine drainage (NMD) and river water in the vicinity of the Anjir Tangeh coal washing plant, Mazandaran province, northern Iran.The NMD water had a neutral pH along with high sulphate and bicarbonate concentrations.

Rare Element Resources needs one more thumbs-up from a federal agency to complete its $53 million rare earth demonstration plant in Upton. The rare earth refinery is billed as a game-changer not just for Wyoming, but America. Improvements being made at the Rare Element Resources site in Upton ...

The term rare earth (RE) is actually a misnomer that shows a cursory view of these metals good enough for a 5-min review (Hurst 2010).Lanthanide series include rare earth elements (REEs) along with scandium and yttrium, being similar in chemical properties and deposited in ores same like REEs (Connelly 2005; Zdzislaw and Agnieszka 2015).Promethium …

Residents blamed a rare earth refinery for birth defects and eight leukemia cases within five years in a community of 11,000 after many years with no leukemia cases. Seven of the leukemia victims ...

The rare earth elements predominantly used in Neo's wastewater treatment product line are cerium and lanthanum. Far from being rare, cerium is the 26th most abundant element in the Earth's crust, while lanthanum is the 29th most abundant. Both are more abundant than nitrogen, cobalt, and lithium. Both are produced by hundreds of companies ...

The ammonium sulphate ((NH 4) 2 SO 4) in-situ leaching process is the most widely used extraction technology for weathered crust elution-deposited rare earth ores (WCED-REOs).Highly concentrated (NH 4) 2 SO 4, a representative leaching agent, is often used in the leaching process of WCED-REOs.However, this in-situ leaching process causes nitrogen …

Rare earth metals are critical to many green energy technologies, including the development of electric vehicles. And for decades, China has played a dominant role in mining, processing and producing them at scale. Beijing has also begun restricting access to them, for trade and diplomatic reasons. The world is now taking note, and looking for alternatives.

This paper presents a study of the removal of ammonia nitrogen (NH3-N) from washing wastewater resulting from the process of rare-earth elements precipitation using struvite precipitation. Experiments were conducted in batches to examine the effect of an excess of magnesium and phosphate on the removal of NH3-N, and to investigate the feasibility of the …

The UK plant will recover mixed rare earth oxides with an expected purity of greater than 90%, which could be refined in a future project to produce individual rare earths and rare earth …
