The mineralogical characteristics of calcium-iron olivines
Mineralogical Magazine and Journal of the Mineralogical Society, 1968SummaryFor the estimation of the properties of calcium-iron olivines in ironore sinters, synthetic mixtures of CaO, FeO, and SiO2 were prepared and melted; the obtained olivines were then examined microscopically and by X-ray powder method. The investigations allowed to state, that with the increase of the basicity of sinters, the relation of Fe : Ca ...

Mineralogical characteristics of electric arc furnace dusts
JOM, 1991Reflected light microscopy can contribute important information regarding the mineralogy, mineral abundance, internal textures, sizes and shapes of particles in electric arc furnace (EAF) dusts. Scanning electron microscopy-energy dispersive spectroscopy and electron microprobe analysis are useful to determine the chemical compositions of the specific ...

Petrographic and Mineralogic Characteristics of Aggregates
1948The petrographic and mineralogic characteristics and geologic occurrence of rock formations and sand and gravel deposits determine the composition, gradation, and quality of aggregates. Thus, because of their several modes of origin—igneous, sedimentary, and metamorphic—rock formations present different problems to the quarryman and produce aggregates ...

Chemical, Mineralogical, and Morphological Characteristics of Pidgeon Magnesium Slag
Environmental Engineering Science, 2016Abstract Pidgeon magnesium slag (PMS) is produced during the production of metallic magnesium by the Pidgeon reduction process, and the disposal of PMS causes serious environmental problems. In this study, the physicochemical characteristics and solubility of PMS were comprehensively investigated.
