Applied Mineralogy in Ore Dressing SpringerLink

Mineralogy applied to ore dressing is a reliable guide for designing and operating an efficient concentrator. A procedure for conducting mineralogical studies in conjunction with ore dressing was, therefore, developed. The procedure includes characterizing the ore and analysing the mill products. Characterizing the ore involves identifying the ...

Ore microscopy (mineragraphy) SpringerLink

The earliest reference to polished-ore techniques is that of Berzelius of Sweden who, about 1806, studied a suite of pyrrhotite-bearing ores with a microscope adapted for reflected light. H. C. Sorby of Sheffield in the 1820s and W. Campbell of the U.S. Geological Survey in the early 1900s developed the technique, which has since found numerous applications in both theoretical mineralogy and ...

"Ore Microscopy Applied to Beneficiation" by Richard D.

Ore microscopy can be an important adjunct to beneficiation, because it can be used not only to predict mill problems of undeveloped ore deposits but to identify the causes for the loss of minerals in the products of operating mines and mills. Mineral distribution among various mill products can be determined by examining polished sections prepared from samples obtained from each step of the ...

The Study of Opaque Minerals in Reflected Light

In the mineral industries, it is employed in studies of mill products aimed at design, improvement, or control of mineral dressing procedures. In ore microscopy, mineral identification is based largely on study of physical, optical, and chemical properties. Physical properties investigated are crystal form and habit, cleavage and parting, scratch hardness, indentation hardness, polishing ...

Comminution is a single- or multistage process whereby ore is reduced from run-of-mine size to that size needed by the beneficiation process. The process is intended to produce individual particles which are either wholly mineral or wholly gangue, that is, to produce liberation. Since the mechanical forces producing fracture are not susceptible to detailed control, a class of particles ...
