【 摘 要 】

Characterization of limestone in Pamekasan Madura island was investigated. So far, limestone at Madura island has low economic value as additional building material. Limestone was taken from three mining locations. The chemical composition of limestone was characterized by X-Ray Fluorescence (XRF), the crystalline phase was characterized by X-ray diffraction (XRD) and morphological investigation was analyzed by Scanning Electron Microscope (SEM). The results XRF tests are obtained limestone with very high purity from Blumbungan, Pamekasan, East Java with Ca content 99,25 wt%. Characterization by using XRD and SEM are showed 100% calcite phase with rhombohedral-cubic shape and a particle size of CaCO3 ranges between 1.594 - 2.503 μm. In conclusion, limestones from Blumbungan are able to material for producing nano precipitated calcium carbonate (NPCC). Furthermore, economic value of limestone in Madura Island are able to advance.
