Dolomite samples collected from the Narpala Mandal region of Anantapur District, Andhra Pradesh, were analyzed to assess their suitability for metallurgical and cement applications using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX). High-resolution SEM imaging at 10 µm, 5 µm, and 2 µm scales revealed distinct rhombohedral crystal morphology, uniform grain boundaries, and minor microporosity indicative of recrystallization. EDX spectra confirmed the dominance of calcium and magnesium carbonates with minor Fe, Si, and Al impurities. The calculated Ca/Mg ratios and low silica concentrations indicate a high-grade dolomite, suitable for use as flux material in steel manufacturing and as a raw additive in cement production. The study demonstrates the value of SEM–EDX techniques in determining mineral purity, microtexture, and industrial applicability of carbonate deposits in semi-arid hard rock terrains.
