Abstract

The amenability and selection of the process for beneficiation of ores are based on the mineralogy and texture of the mineral, type of impurities present in it and the mode of association of gangue and value minerals, their liberation characteristics etc.In order to identify the minerals and the association of valuable ore mineral with the gangue, characterisation studies of low grade magnesite of Parshad area, Udaipur district, Rajasthan were undertaken. Petrography, physicochemical characteristics, DTA, TGA, DTGA, vitrification study and X-ray analysis were carried out to characterise the magnesite.The characterisation studies reveal that the magnesite ore is mainly composed of magnesite with minor amounts of quartz and iron. Other minerals, namely, calcite, sericite and clinozoisite are present in traces. Based on the studies, the possible beneficiation route was identified.
