Its mineral composition is similar to that of the ordinary portland cement clinker, but it is characterized by high C 3S content, more than 70% (in mass) of C 3S contained based on the whole mineral composition.
This rock is characteristic of inequigranular giant grains, pseudoporphyritic texture and massive structure. Its mineral component is predominantly forsterite with grain size 20-30mm generally, and above 100mm at maxi-mum.
Gold (Ⅲ) chloride and gold (Ⅰ) thiosulfate adsorption by various minerals and ores were experimented and studied in the paper. The adsorption of AuCl - 4 by minerals is much higher than Au (S 2O 3) 3- 2. The adsorption is montmorillonite>kaolinite>illite for clay minerals, and pyrite>goethite>limonite for iron bearing minerals.
Experimental results demonstrated that these nanophase minerals could inhibit the proliferations of U2OS significantly.
Detailed rock magnetic results show that the magnetic minerals of the sediments were dominated by ferrimagnetic minerals such as magnetite, and a small contribution of hematite and maghematite also existed.
X-ray diffraction investigation of native Si-Fe alloy minerals from Luobusha, Tibet
The powder diffraction pattern shows that the minerals are composed of FeSi, FeSi2, β-FeSi2 and native silicon.
The association of these minerals suggests that the crystallization order of the mineral may be from early to late FeSi→FeSi2→native silicon, accompanied by gradually increasing deoxidization.
It is demonstrated that the mineral field of a proximal polymineral placer is extremely disordered; its mineral assemblages primarily reflect the provenance rock composition and only insignificantly the formation environment of the placer itself.
Composition design for high C3S cement clinker and its mineral formation
In addition, the concentrations of noble gases in lunar soil also show a close relationship with its mineral and chemical compositions.
The genetic origin of the mineralization characterized by intense silicification and absence of simple carbonates is related to a hydrothermal stage of carbonatitic differentiation by its mineral assemblage and its geochemistry.
Implications for a large hydrothermal system within a volcanic pile are discussed in relation to the Ordovician Lukavice Group and its mineral deposits and to some other parts of the Bohemian Massif with volcanosedimentary sequences of the same age.
