In the Figure1, the phases in the iron ore sample are identified as goethite, kaolinite, hematite/ martite, magnetite and braunite. The limitation of the technique is for the minerals whose volume percentage is less than 3% in the sample Some of the trace phases of very small size can not be studied by optical microscopy or XRD. In

It was observed that after grinding, calcined clays exhibit a strongly bimodal particle size distribution, where the clay minerals concentrate mainly in the finer particle population. Particle classification (air separation) techniques were applied to remove the impurities (mainly quartz and iron oxides) and therefore, increase the amount of kaolinite in the resulting material.
The mechanical grinding treatment destroyed the ordered sheets of kaolinite, formed fine fragments and generated broken bonds (undercoordinated metal ions). These broken bonds served as new sites ...
Minerals of research grade, including quartz, calcite, kaolinite and pyrite, were ground to 325 mesh for this study. Grinding was carried out in a ceramic mill to avoid magnetic contamination. Kaolinite was prepared with a blender to eliminate oxidation problems, pyrite samples were washed with dilute hydrochloric acid and dried before grinding.
metakaolinite, an activated phase of kaolinite by calcination at around 650°C, has been widely used as a convenient starting material for the synthesis of zeolite with low silica content such as NaA, NaX and 7) Mechanical treatment by dry or wet grinding of natural minerals is of great interest in the preparation and processing

while grinding kaolinite in an oscillating mill. The results showed that, at a certain stage, the ground material tends to agglomerate due to the high surface energy produced in the grinding process. The adherence of the ground particles to the surface of the jar and ofthe grinding .
Figure is a general flow diagram for metallic mineral processing. Very few metallic mineral processing facilities will contain all of the operations depicted in this figure, but all facilities will use at least some of these operations in the process of separating valued minerals from the matrix rock.
