Jan 12 2010 · The iron ore samples have been investigated by optical microscopy EPMA XRD and TGDTA The optical microscopy studies have indicated three dominant textural types of goethite such as a colloformbanded vitreous b massive vitreous and c earthy or ochreous goethite

In this paper it is elucidated that how process mineralogy knowledge can be used in mining and ore dressing stages and its importance in mineral processing by giving examples

For liberation analysis using MLA the sample in the form of fine particles from mineral processing plants needs to be set in an epoxy resin in a round mould to form a hardened block and a cross section of which is polished coated with carbon before presented to the system

Process Mineralogy Particle size distribution of minerals All of these factors are ore bodyspecific and they also vary from processing step to processing step in a plant The insight provided into these factors makes automated mineralogical analysis by scanning electron microscope SEM an indispensable tool in the modern metallurgist’s
