Detection of rare earth element anomalies in Esfordi ...

This study is aimed to determine geochemical anomalies of rare earth elements (REEs) and provides a concentration distribution map for the Esfordi phosphate deposit (EPD), Bafq metallogenic province (BMP), Central Iran. With an average grade of 5519 ppm for REEs, the EPD is one of the prominent deposits of the region. In this research, sequential Gaussian simulation (SGS) and concentration ......

VolcanoPhos Rock Phosphate

Igneous rock provides a different suite of trace minerals compared to sedimentary rock primarily in rare earth elements while being lower in aluminum content. It meets the NOP (National Organic Program) requirements for use on certified organic farms as a clean mineral source to aid as a soil amendment....

earth rare earth elements in rock phosphate

Rare earth elements in sedimentary phosphate deposits. The critical role of rare earth elements (REEs), particularly heavy REEs (HREEs), in hightech industries has created a surge in demand that is quickly outstripping known global supply and has triggered a worldwide scramble to discover new sources....
