Calcium uranyl carbonate, chemically represented as CaUO2(CO3)3, is a rare secondary uranium mineral utilised in nuclear processing and geochemical sectors. In uranium extraction processes, it emerges transiently during carbonate-based leaching of low-grade ores, where it aids in solubilising uranium(VI) before redissolving for downstream purification via solvent extraction or ion exchange.

Its complexes are important in environmental science, especially for uranium (U(VI)) management, acting as stable, mobile forms in water, influencing remediation of contaminated sites. Additionally, these complexes show potential in nanomaterial research for contaminant removal (like arsenic) and even hydrogen storage.

The market demand for calcium uranyl carbonate is driven by its role in nuclear processing and geochemical sectors. The rising global demand for nuclear energy, fuelled by clean power transitions and investments in reactors, boosts uranium processing, where this compound forms during carbonate leaching of ores, enhancing extraction efficiency before purification.

Additionally, surging uranium mining investments, technological advances in in-situ recovery, and government policies supporting nuclear infrastructure in regions like North America, Asia-Pacific, and Europe, indirectly elevate its relevance in fuel production and waste management. However, strict nuclear safety and radiation controls limit supply chains to licensed handlers, influencing industrial calcium uranyl carbonate procurement. Furthermore, uranium price volatility and geopolitical supply risks from major producers like Kazakhstan, Canada, and Australia disrupt feedstock availability and affect the overall procurement.

Raw Material for Calcium Uranyl Carbonate Production

According to the Calcium Uranyl Carbonate production plant project report, the various raw materials for Calcium Uranyl Carbonate production include uranyl nitrate and sodium carbonate.

Production Process of Calcium Uranyl Carbonate

The extensive Calcium Uranyl Carbonate production cost report consists of the following major industrial production process:

1. Production via controlled precipitation: The production process of calcium uranyl carbonate (CaUO2(CO3)3) occurs via controlled precipitation by titrating uranyl nitrate (1.0 M UO2(NO3)2·6H2O) into stirred sodium carbonate (0.3 M Na2CO3) to generate soluble UO2(CO3)3^4- complexes. The reaction is followed by the addition of calcium nitrate (4.0 M Ca(NO3)2·4H2O) and pH adjustment to 8.1, producing pale green crystals along with minor calcite after 2-3 weeks of slow evaporation at 25 degree Celsius. The process involves precise U:CO3:Ca stoichiometry (1:3:1-2), pH 7-10 stability window to favour ternary complexes over hydrolysis or excess CaCO3, and ultrapure reagents for high purity (>90%) confirmed by single-crystal XRD with SQUEEZE solvent modelling.

Properties of Calcium Uranyl Carbonate

Calcium uranyl carbonate (CaUO2(CO3)3), also known as liebigite in mineral form, appears as bright yellow-green to pale yellow crystalline solids with a vitreous to pearly lustre, transparent to translucent habit, and a white streak. It has pale green fluorescence under UV light and possesses a Mohs hardness of 1½-2 with brittle tenacity and perfect cleavage. It consists of a layered structure of uranyl tricarbonate sheets [(UO2(CO3)3)^4-] linked by Ca²⁺ cations and water molecules. It is sparingly soluble in neutral water (due to neutral Ca2UO2(CO3)3(aq) complex stability) but highly soluble in alkaline carbonate solutions, where it redissolves as UO2(CO3)3^4- or ternary species. Its density ranges ~3.8-4.2 g/cm³, with thermal decomposition above ~200 degree Celsius yielding UO3, CaCO3, and CO2. It is stable in pH 6-10 Ca-rich oxidising environments but hydrolyses below pH 6 or destabilises at elevated temperatures, with nanoscale cage clusters observed in aqueous solutions via ESI-MS.
