  • Assessment of rare earth element potential in intrusive rocks special reference to massenna zircon granite 
    Jayasuriya, JHAATS; Jayathilake, RGMA; Jeyakumar, J; Batapola, NM; Dushyantha, NP; Abeysinghe, AMKB; Premasiri, HMR [Conference-Full-text]
    Sri Lanka has a geological setting that favors the presence of rare earth elements (REEs), which are currently identified as the most critical and strategic elements in the world. Previous geochemical studies show that ...
  • Feasibility of extraction of cerium dioxide (CeO2) from monazite at Pulmoddai 
    Rasanjalee, PHAU; Delaksana, S; Sampath, MD; Dushyantha, NP; Batapola, NM; Dissanayake, DMDOK; Rohitha, LPS [Conference-Full-text]
    Monazite concentration in Pulmoddai mineral sand deposit in Sri Lanka is 1.38%. Its Rare Earth Elements (REE) composition is about 61%. Currently, only heavy minerals are separated and cerium rich monazite is discarded. ...
  • Rare earth elements exploration in river sediments (Belihul oya and Samanala wewa areas, Sri Lanka) 
    Dilshan, MWRR; Prabhashan, HPM; Kalaishanthan, K; Dushyantha, NP; Batapola, NM; Premasiri, HMR; Abeysinghe, AMKB [Conference-Full-text]
    The global REE deposits are mostly associated with carbonatites, alkaline igneous rocks, ion adsorption clay deposits and placers. In this context, previous geochemical studies of alluvial beds in Sri Lanka have disclosed ...
  • REE Potential in carbonatite deposits: a case study of Eppawala carbonatite 
    Batapola, NM; Dushyantha, NP; Premasiri, HMR; Abeysinghe, AMKB; Rohitha, LPS; Ratnayake, NP; Dissanayake, DMDOK; Ilankoon, IMSK; Dharmaratne, PGR [Conference-Abstract]
    Rare earth elements (REEs) are currently the most strategic elements in the world due to their significance in the diversified technological applications. Currently, a total of 478 million tonnes of REE resources is ...
