In an ideal structure of dolomite, alternating layers of Mg 2+, Ca 2+ are interspersed with CO 3 2− groups oriented normal to the c-axis (Fig. 1), with a Mg/Ca molar ratio of 1 (stoichiometry) and an ordered arrangement.The larger radius Ca 2+ occupy A sites and the smaller radius Mg 2+ occupy B sites. The standard unit cell parameters of …
Coal mining processing plant in Nigeria. This coal mining project is an open pit mine located in Nigeria, announced by mining company - Western Goldfields - that it has discovered 62,400,000 tonnes of proven reserves of coal deposits worth US$1.2 billion which could be used for the generation of electric power...
The use of a twin-screw extruder for processing a thermoplastic/dolomite composite can provide a greater shear force to de-agglomerate the dolomite, thus assisting in its dispersion in the matrix. In contrast, the casting process or manual stirring used to process the thermoset/dolomite composite cannot provide enough shear to allow …
