Potential of eppawala apatite as a directly applied low

Jun 01, 1995· Apatite in Sri Lanka is mined from Eppawala (Eppawala Rock Phosphate or ERP). The finely ground product is used as a direct application fertilizer for tea, rubber and coconut. ERP is an indiscriminate mixture of more soluble primary crystals and a less soluble secondary phosphate matrix rich in ferruginous and aluminous compounds with an average P2O5 content of 30%.

Identifying the competence of delineating the subsurface

This method is commonly used for mineral exploration in many countries though Sri Lanka is yet to apply the same in detail. Despite few attempts on iron-ore deposits, this method has never been applied for identifying any other mineral commodity such as apatite. Instead, identifyingthe subsurface extension of mineral deposits is largely based on

Use of Carbonatites in the Production of Precipitated

Sep 26, 2013· We made use of fresh apatite-rich carbonatites found at the phosphate mining sites at Eppawala, Sri Lanka. Analyses of the fresh carbonatite were performed with the aid of optical microscopy, powder X-ray diffraction (XRD), atomic absorption spectrophotometry (AAS), UV/visible spectrophotometry (UVVS), and thermo gravimetric analysis (TGA).
