Dear Colleagues, It is our pleasure to announce a Special Issue of Minerals entitled "Crystallochemistry and Geochemistry of Dolomite". Dolomite, CaMg(CO 3) 2, is an ubiquitous carbonate mineral in the Earth crust which plays a key role in the carbon and magnesium global cycles.Since its discovery at the end of the 18th century, dolomite as …

agent. Dolomite coarse aggregate can also be used for per-meable concrete production [51]. Sernas et al. [52] used dolomite as aggregate in the asphalt mix for pavement and found promising results. The sand brick can also be made by using dolomite quarry waste as a sand replacement at 0%, 25%, 50%, 75%, and by the weight of sand con-tent …

Polymers are being used in many applications all around the world. However, there are some drawbacks in the properties of polymers that could hamper their usage in certain applications. Therefore, a new material polymer composite was introduced. A polymer composite is a polymer-based material with the addition of a filler. Many …

Dolomite exhibits a wide distribution in geological strata. The metabolic activities of microorganisms in marine sediments play a crucial role in the formation of dolomite. Semiconducting minerals, such …

Although mining contributes to about 1.4% of Fiji's gross domestic product (GDP), the excavated rocks from mining may have detrimental effects on the environment. In this study, rock samples from five Fiji mine sites were selected to assess their geochemical characteristics from an environmental point of view. The mineralogical and …

PMSC-Alcoy Plant holds a mineral processing permit by the MGB, which will expire in 2023. ... Garcia also cited the lack of an environmental impact study (EIS) on the extraction of minerals from ...

Background The size of lime material is vital for the efficiency of ameliorating soil acidity, thereby influencing soil biochemical processes. However, the effects of different sized lime material application on soil organic carbon (SOC) mineralization are yet to be elucidated. Therefore, a 35-day incubation experiment was conducted to determine the …

Dolomite, a calcium magnesium mineral (CaMg(CO3)2), is considered an undesirable accompanying mineral in the phosphoric acid production process and, as such, large quantities of this mineral are available in Florida. This study is aimed toward the characterization of the high-concentration phosphatic dolomite pebbles (handpicked …

The utilization of dolomite by-products quarries waste as a microfiller and substitute of aggregate in concrete decreases environmental impact and makes highly …

Mining is known to be associated with several environmental impacts, such as negative effects on local wildlife and vegetation, loss of habitats, effects on water availability and quality, altered ...

to the impact of environmental pollution. Hence, treating the pond water for nutrient reduction before ... On the use of dolomite as mineral filler and co-filler in the field of polymer composites ...

The production of dolomite minerals in Environmental assessment, microstructural behaviour, stress–strain characteristics, and effect of exposure to …

The flotation separation of magnesite from calcium-containing minerals has always been a difficult subject in minerals processing. This work studied the inhibition effects of carboxymethyl cellulose (CMC), sodium lignosulphonate, polyaspartic acid (PASP) and sodium silicate on flotation behaviors of magnesite, dolomite and calcite, providing …

This review article aims to study the socioeconomic and environmental aspects of limestone mining in Tuban Regency. Limestone mining by the village community substantially meets the eligibility ...

Dolomite CaMg(CO 3) 2 is a thermodynamically stable carbonate mineral that composes about 30% of the sedimentary carbonate mineralogy in Earth's crust (1–3).Despite its geochemical abundance, nearly two centuries of sustained scientific efforts have failed to precipitate dolomite in the laboratory near ambient conditions ().One …

Abstract. Dolomite (CaMg (CO 3) 2) plays a key role in the global carbon cycle. Yet, the chemical mechanisms that catalyze its formation remain an enigma. Here, using batch reactor experiments, we ...

The advances of new and improved analytical approaches have led to a significant increase in proxies applied to dolomite research (e.g., δ 44/40 Ca/δ 44/42 Ca, δ 26 Mg, δ 11 B, δ 88/86 Sr, clumped isotopes). In recent decades, a growing number of studies have applied multi-proxy isotope approaches by combining traditional and non ...
