Industrial minerals play an important role in keeping our society running, as they are used a wide range of industrial and domestic applications [...]
A range of industrial minerals was tested using the rotating drum and the continuous drop methods, the two methods proposed by the published European standard EN 15051 [CEN. (2006) EN 15051 Workplace atmospheres—measurement of the dustiness of bulk materials— requirements and test methods. Brussels, Belgium: European Committee for Standardization], to evaluate and compare their dustiness. The a...
The desirable physical and physiochemical properties of clay minerals have led them to play a substantial role in pharmaceutical formulations. Clay minerals like kaolin, smectite and palygorskite-sepiolite are among the world's most valuable industrial minerals and of considerable importance. The elemental features of clay minerals which caused them to be used in pharmaceutical formulations are...
Flotation is the single most important method of mineral processing and is widely used for the concentration of metal ores, industrial minerals, and coals. Several investigations were carried out during the last century, and the flotation literature was immense, particularly on selective collectors and their interaction mechanisms on sulfide, oxide, and silicate minerals. However, it is often d...
The processing mineralogy characteristics of an oxidized lead-zinc ore from Sichuan were studied systematically using numerous modern instruments. Results showed that lead and zinc oxide content in the ore exceeded the minimum industrial grade, and also included a relatively high concentration of silver and iron. This ore is composed of many different minerals. Major zinc-containing minerals in...
Fibrous minerals are common in nature but asbestiform minerals are rare. The unique mineralogical characteristic common to all the asbestos minerals is their morphologic form (or habit of crystallization) as polyfilamentous fiber bundles. The individual fibrils within the bundles have a tendency to be very long with a narrow range of diameters and grow with their long fiber axis in parallel ori...
Electron microscopes (SEM, TEM) and electron microprobe (EPMA) are useful research equipments that can be used to examine the mineral raw materials and also their industrial products and defi nite ly through the produc ti on process of tr a nsform ing the minerals to industrial products. These are useful equipmen ts, that can provide all the information about weakly crystaline minerals t...
