Reaction mechanism of dolomite powder in Portland-dolomite cement
Construction and Building Materials, 2021The purpose of this study is to provide a better understanding of the reaction mechanism of dolomite powder in Portland-dolomite cement (PDC). The hydration products and microstructure of PDC pastes were investigated by using XRD, TGA, MIP, and SEM, with

The role of sodium alginate in the flotation separation of apatite and dolomite
Powder Technology, 2020In this study, a selective depressant sodium alginate (SA) was used to improve the flotation performance of separating apatite from dolomite. The flotation results show that SA can completely depress dolomite with a slight effect on apatite flotation in ...

Estimation of Dolomite Formation: Dolomite Precipitation and Dolomitization
Journal of the Geological Society of India, 2016 Abstract: Reactive-transport models are developed here that produce dolomite via two scenarios: primary dolomite (no CaCO3 dissolution involved) versus secondary dolomite (dolomitization, involving CaCO3 dissolution). Using the available dolomite precipitation rate kinetics, calculations suggest that tens of meters of thick dolomite ...

The thermochemical activity of dolomite occurred in dolomite–palygorskite
Applied Clay Science, 2016Abstract Dolomite–palygorskite (DP) composed of dolomite and palygorskite is a kind of special palygorskite. In this work, the phase, microstructure, and morphology of DP were characterized before and after calcination using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM ...

Dissolution enables dolomite crystal growth near ambient conditions
Science, 2023Crystals grow in supersaturated solutions. A mysterious counterexample is dolomite CaMg(CO3)2, a geologically abundant sedimentary mineral that does not readily grow at ambient conditions, not even under highly supersaturated solutions.
