Ore minerals not only can be distinguished from a matrix of rock-forming minerals, but in many cases, differentiation of the metallic mineral species can be accomplished. Further, algorithms have been developed to produce quantitative information on grain size, shape, and textural relationships (e.g. Godel, 2013, Ketcham, 2005, …

The study of ore minerals is rapidly transforming due to an explosion of new micro- and nano-analytical technologies. These advanced microbeam techniques can expose the physical and chemical character of ore minerals at ever-better spatial resolution and analytical precision. The insights that can be obtained from ten of today's most …

Ore grade estimation is a key aspect in the evaluation of a mineral deposit. In this paper an alternative approach to currently applied methods of ore grade estimation is presented.

Natural or artificial light allows us to see and analyze matter with our eyes, which are the first tools used in several experiments. In geosciences, particularly in mineralogy, light is used for optical microscopy observations. Reflected and transmitted light applied to the study of ore deposits can be useful to discriminate between gangue from …

If the internal atomic arrangement is lacking, then it is an amorphous substance. A rock is generally composed of various minerals and if the rock contains valuable minerals frOm which metals can be extracted at a profit, it is called an 'ore'. The unwanted mineral in an ore is called gangue (i.e., generally rock forming minerals). For ...

1. Ore quality can be defined as the set of physical indicators of the ore which determines the level of extraction of valuable components from the ore in a particular technical process. 2. The most important indicators of ore quality are the contents of the metal extracted, the grain size of the mineral extracted, and the phase composition of the metal. 3. The main …
