portland cement clinker was ground in plant and laboratory ball mills to examine the effect of grinding in different mills on the cement properties. Mineralogical examination showed that in the plant mill (1200 cm X 260 cm), because of the rising temperature during grinding, gypsum was de hydrated to hemihydrate, while

The main constituents of blast furnace slag are CaO, SiO2, Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further dried and ground in a rotating ball mill to form a fine powder, known as ground granulated blast furnace slag cement.

A combined mineralogical study by polarising microscopy, scanning electron microscopy, cathodoluminescence microscopy and spectroscopy, and electron backscatter diffraction provided evidence that the spirals consist of wellordered trigonal αquartz, whereas the surrounding matrix is composed of strongly disordered or amorphous SiO 2 phases. The quartz microcrystals show a .
In late 1975, the company donated the Federal minemill complex, along with adjoining lands, to Missouri for use as a state park. The Missouri Department of Natural Resources took possession of the 8,244acre tract in 1976, subsequently naming it St. Joe State Park .

periodic mineralogical analyses of ore feed and mill products are needed to determine the nature of the problem if the gold recovery is lower than expected. Therefore, a routine process mineralogical study of gold ores normally includes some or all of the following objectives:1 • .
The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
