Researchers have examined a method to extract rare-earth elements from mining waste that could provide the world with a reliable supply of the valuable materials. The research, led by Idaho National Laboratory and Rutgers University with support from the Critical Materials Institute, is online and in an upcoming issue of the Journal of Chemical ...
To meet the growing global demand for rare earth elements (REEs), nontraditional mining sources of these metals are being investigated. Phosphate ore and phosphate mining wastes have been identified as possible alternative sources to REEs. In this study, REEs were extracted from Florida phosphate mining materials using mineral and organic acids. The REEs were then recovered at high ...
Rare Earth Elements in Phosphate Matrix There are Rare Earth Elements in the phosphate matrix mined by Mosaic. The Rare Earths associated with phosphate matrix are primarily found in: • Clays o Mosaic produces a total of approximately 13.5 million tons of clays per year at the active mines in central Florida which contain approximately 4,813 ...
The exploitation and smelting of rare earth resources lead to serious pollution of rare earth elements (REEs) in farmland around mining area. The influence of four kinds of phosphate amendments-phosphate rock (PR), superphosphate (SSP), bone char (BC), and calcium magnesium phosphate (CMP)-on the bioavailability of REEs and the uptake and accumulation of 15 types of REE in rice …

Glenover's focus is to deliver a high quality world class, multi-commodity project in the form of a large fertiliser and rare earth complex situated coastally. It aims to access the growing East African, Indian and Pakistani agricultural markets as well as the global rare earth markets". No mining costs for the first. 7 years of production.
These metals, known as rare earth elements and found in phosphate and other rocks, are a vital component in wind turbines, electric vehicles and smart phones, but are now mostly imported from China. The United States mines and uses about 23 million tons of phosphate rock per year, according to the U.S. Environmental Protection Agency.
Rare earths filtered from phosphate mine waste. In recent tests US start-up Precision Periodic, which has developed a mining filtration system, extracted 80% of the total rare earths from phosphate mine waste in a five-minute, single pass. Precision Periodic conducted rare earth extraction projects for Florida Industrial and Phosphate Research.

1.Introduction. Rare earth element based technologies underpin an increasingly broad range of industrial sectors (Long et al., 2010, Service, 2010).These elements, grouped because of their chemical and physical similarities, include the 14 naturally occurring lanthanides, and yttrium (Y) (Long et al., 2010).Here, as increasingly common in the resources …
Phosphogypsum, a source for rare earth elements, is a waste product from phosphate rock mining, is watery at first and forms a crust as it dries. (Image source: US Environmental Protection Agency) There are a variety of sources for rare earth elements, including hard rock mining and purification from sediments.
