The Morphology and Metallurgical Implications for Extraction of Platinum Group Minerals (PGM’s) in Chromitite
- 1 Downloads
This study was carried out on chromitite bearing samples from Sittampundi anorthosite complex (SAC), Tamil Nadu, to understand the morphology of platinum-group minerals (PGM) and associated silicates using state-of-the-art technology QEMSCAN®. The dominant mineralogy of the samples are chromite (>70 mass percent), plagioclase (An90) and chlorite-actinolite with orthopyroxene (En85). The morphology of PGMs grain sizes are varying from 10 − < 3µm in size. Understanding the morphological characteristics of PGMs is essential for the future beneficiation and metallurgical process involved for the extraction of PGMs associated with the chromitite samples to make viable Sittampundi complex a promising target for future PGE exploration.
