Earlier this month, the Department of Environment and Natural Resources (DENR) pushed through with its plan of covering a 500-meter stretch of Manila Bay's shoreline with dolomite sand—a move that drew both praise and criticism. Unbeknown to many, dolomite is actually all around us. It is frequently used in the production of concrete ...

Dolomite's sedimentary origins, involving the alteration of limestone by magnesium-rich fluids, result in a rock with distinct mineral properties and uses. This difference in formation contributes to their varied applications in industry and construction.

Through a major mining project, the Environmental Impact Assessment exposed the difficulties often encountered in implementing regulatory controls in all new mining ventures in Kenya, both large ...

practice is usually performed for the amelioration of acidic soils, but the effects of dolomite application on N 2 O emissions from acidic soils are still not well understood. Therefore, a laboratory study was conducted to examine N 2 O emissions from an acidic soil following application of dolomite.

Both valuable (apatite) and gangue mineral (calcite/dolomite) are prone to interacting with fatty acid collectors because of the similar calcium active sites existing on the cleavage planes, resulting in the low selectivity of …

Dolomite, a common alteration product of Ca-carbonate minerals through interaction with seawater in diagenetic environments, is often seen as an unlikely candidate to preserve primary redox ...

Dolomite, as a common mineral in nature, has a wide range of applications in the chemical industry, metallurgy and construction; however, its formation has puzzled researchers for centuries.

To enhance the removal and separation efficiency of Sr ions from simulated radioactive wastewater, the use of dolomite mineral as environment-friendly absorbent with the aid of ball milling is proposed.

This review article aims to study the socioeconomic and environmental aspects of limestone mining in Tuban Regency.

The Department of Water Affairs has devel-oped a detailed guideline for the Assessment, Planning and Management of groundwater in those parts of South Africa underlain by dolo-mite rocks. The Council for Geoscience and the Department of Public Works have also pro-duced documents on dolomite areas, but fo-cusing more on the development of …

Dolomite Testing. Dolomite consists of calcium magnesium carbonate and hence is called a carbonate mineral. Dolomite rock and dolostones are used interchangeably to refer to the sedimentary carbonated rock that is primarily composed (approx 90%) of dolomite minerals. Dolomite is used commonly in the construction industry, in mortar and …

The crystal structure and genesis of dolomite record fundamental geochemical and environmental processes of significance in the Earth's element cycle process, carbon storage, and paleoenvironments, with relevance to the exploration for minerals and fossil fuels, management and maintenance of the environment, and the …

In the field of mineral processing, the successful flotation of target minerals requires sufficient liberation through grinding. The aim of this paper is to compare and evaluate the performance of ball versus short cylindrical media for comminution of dolomite by point and line contact, respectively. The results of the grinding experiments indicate …

Semantic Scholar extracted view of "Synergistic impact of surfactant and sodium oleate on dolomite removal from fluorapatite via reverse flotation" by Shengzong Lan et al.

The present chapter will review the environmental impact of nitrogen fertilization by analyzing the effects caused by the interactions of the technological and environmental subsystems.

Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the …

Impacts of Beach Nourishment using Dolomite Sand Dolomite is a naturally occurring mineral and has a low carcinogenic level to humans. However, this can be amplified in the food chain through other marine species.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the …

Palaeo-environmental conditions can be recorded in low-temperature continental archives, according to geochemical and isotopic analyses of dolomitic fracture infills at Erzberg, Austria

The use of rare earth elements in various technologies continues to grow despite some alternatives being found for particular uses. Given a history of ecological concerns about pollution from rare earth mines, particularly in China, there are growing social and environmental concerns about the growth of the mining and mineral …

This legislation establishes guidelines for environmental management and impact assessments, which apply to dolomite drilling projects. It requires environmental authorisations to be obtained before conducting drilling activities. This act governs the exploration and exploitation of mineral resources in South Africa, including dolomite.

It is suggested that carbonate mineral dolomite, not sphalerite, is the predominant Cd host mineral in Niujiaotang Cd-rich Zn tailing. This provides a new insight into the environmental impact of cadmium on MVT zinc deposit, because it is rich in cadmium and widely distributed around the world.

This review paper has discussed the use of dolomite powder in concrete and their effects. Furthermore, the paper has examined the origins and uses of dolomite.

The company carries out every process of dolomite mining and processing with as little environmental impact as possible, in accordance with the latest technical standards.

Environmental assessment, microstructural behaviour, stress–strain characteristics, and effect of exposure to extreme temperature on sustainable concrete made with dolomite mining residues

Calcite, like many minerals, can have both positive and negative environmental impacts depending on how it is utilized and how its interactions with the environment are managed.

This article illustrated the microscopic pore structure and distribution of the argillaceous dolomite reservoir, discussed the porosity enhancement potential through dolomite mineral dissolution by organic acids, and indicated the contribution of the dolomite mineral dissolution pores to the porosity.

The results demonstrate that the size of dolomite is a key factor in regulating SOC mineralization in acidic paddy soils when dolomite is applied to manipulate soil pH.
