dc.description.abstractPhosphorus is one of most important plant nutrients because its function cannot be performed by any other nutrient. Phosphate fertilizer is mainly produced from the natural phosphate rocks worldwide. Phosphate deposit at Eppawala is one of the most economically valuable mineral deposits in Sri Lanka. It contains up to 42% of P2O5 while the citric acid solubility of various components varies from 4% to 6%. Due to strong weathering of apatite-bearing parent carbonatite rock, an economically valuable secondary phosphate deposit has formed (Subasinghe, 2013). Former studies revealed that iron leaching from weathering parent rock played an important role in fixing phosphate and formation of secondary deposit through in-situ diagenesis (Subasinghe, 2012). Source of iron is assumed to be magnetite and other iron bearing minerals. To reap grater benefits from the deposit it is necessary to produce value added products such as triple super phosphates. Due to considerable amount of iron impurities from magnetite and other iron baring minerals, the production of super phosphate may pose some difficulties at industrial level. The objective of this study is to develop a methodology to estimate the magnetite, the main iron- bearing mineral, in the phosphate ore.en_US
