Approximately >50% of global rare earth element (REE) resources are hosted by carbonatite related deposits, of which monazite is one of the most important REE minerals. Monazite dominates more than 30 carbonatite-related REE deposits around the world, including currently exploited mineralization at Bayan Obo and Mount Weld. These …
Neo and Energy Fuels have been working in a technical collaboration since April 2020 to establish a monazite processing and RE Carbonate production capacity at Energy Fuels' White Mesa Mill plant. As previously announced, Energy Fuels successfully produced RE Carbonate at the White Mesa Mill in October 2020 from monazite sands.
Monazite is a poorly soluble mineral of rare earth phosphate. It is an ore of the rare earths which is difficult to break down; in industry either concentrated sulphuric acid or caustic soda is used to attack finely ground monazite at between 140 °C and 400 °C. In these processes, the rare earths are converted into different solid compounds, …
