Nodular monazite occurs in metamorphic rocks worldwide and has zonal REE patterns. This paper focuses on the composition of nodular monazite hosted by Permian black shales of the Kular Ridge in the Kular-Nera terrane. This monazite variety (called kularite in the Russian literature) reaches comm...detailed
Rare earth elements (REE) are key components of many emerging green technologies. This leads to an increase in demand for REE, hence to the development of new deposits, such as the Niobec carbonatite rare earth deposit in Quebec, Canada. One of the valuable minerals in this deposit is monazite, ...detailed
The adsorption of carboxylate collectors is largely assumed to be affected by the monazite surface speciation. In order to provide key information for the understanding of this phenomenon, we propose in this study a thermodynamic model for the equilibrium of monazite-(La) crystal in an H2O-CO2 s...detailed
The Manangotry area in the South-East of Madagascar is famous for its giant monazite crystals. The studied occurrence is an outcrop near the Manangotry pass, were giant, cm-sized crystals have been found. The crystals are embedded in biotitite levels, also containing cm-sized xenomorphic ilmenit...detailed
The present paper reports an improved process using cheaper reagent at atmospheric conditions compared to the expensive pressure leaching technique (Temperature = 140 °C) as well as other processes available at higher temperature. An effective baking reagent, potassium hydroxide (KOH) was used ...detailed
