Importance of Microscopic Studies in Mineral Dressing
2012-7-24 MINERAL dressing is primarily a process of separation of minerals by physical methods, involving little or no chemical change. A thorough understanding of the identity and texture of minerals present in an ore is, therefore, a pre-requisite to any attempt to separate one mineral from the other. Mineralogical examination of an ore often provides
