A high-fidelity filter to honor the control point value and smoothing on surfaces were also applied as geoprocessing options. The employed algorithm and adopted interpolation options ensure that the extrapolated value would gradually approach the nearest sampling point data, respecting the value of the measured variables.
Sustainable development is defined in Quebec legislation (Loi québécoise sur le développement durable, chap. Ι, art. 2) as follows: Figure 1illustrates … See more
In 2021, Chinese researchers Tian, J. et al. put forward a new process for the comprehensive utilization and safe disposal of arsenic and alkali slag combining …
All of the arsenic is imported from China and Morocco. Arsenic can be toxic in large doses,and the mining industry monitors and prevents its release into the environment. Background. Arsenic is the 20th most abundant component in the Earth's crust, and is widely distributed in rocks, soils, natural waters, and small amounts in most living things.
We provide an overview of arsenic (As) from gold mining spoils, tailings disposal sites, and mining degraded soils and propose sustainable soil remediation …
Abstract. Pollution from potentially toxic metalloids such as arsenic is becoming a major concern for living organisms all over the world. Arsenic (As) is a non-essential metalloid in plants that can build up to toxic levels. As-contaminated soil remediation ought to be sustainable, low-cost, and applicable in the most vulnerable low …
This article provides a detailed analysis of strategies for treating steel industry waste in wastewater treatment. Recent advancements in membrane …
Under CESL pressure leaching conditions (150°C, 1380kPa) high copper extraction and arsenic fixation as scorodite is possible. Arsenic control in the copper industry ultimately needs an integrated approach involving each stage of the value chain, i.e. exploration, mine operation, refining process and mine closure.
Mining wastes, particularly in the form of waste rocks and tailings, can have major social and environmental impacts. There is a need for comprehensive long-term strategies for transforming the mining industry to move toward zero environmental footprint. "How can the mining industry create new economic value, minimise its social …
Regulating these activities mainly depends on national frameworks and policies, but implementing good practices remains problematic. To truly shift to "sustainable mining," governments and companies must recognize the social impacts of mining, and enact laws and regulations that require community consultation throughout the life of a …
integrated approach to effectively control the arsenic is the key to a profitable and sustainable operation, in full regulatory compliance. INTEGRATED APPROACH FOR ARSENIC CONTROL The improvement of the environmental performance of the mining industry with regards to arsenic is based on an integrated approach involving every …
Additionally, because the development of the sustainable mining concept is industry driven, searches were performed for published standards and legislation in areas beyond peer-reviewed publications. Of these industry or governmental initiatives, North-American-focused as well as global results were included.
Superfund risk assessments and the resulting soil arsenic (As) cleanup levels selected for mining sites are currently based on the toxicity of soluble As in drinking water. However, …
In this regard, we systematically reviewed the recent literature (n=200) from the last two decades regarding As bioremediation potential of conventional and recent technologies including genetically modified plants for phytoremediation and integrated approaches. Also, the responsible mechanisms behind different approaches have been identified.
Arsenic is one of the well-known heavy metals that can be detected at low concentrations in the environment. Inorganic forms of arsenic are tetravalent and …
Although many have defined and applied the concept differently (see Fig. 1), sustainable development, generally, is the combination of enhanced socioeconomic growth and development, and improved environmental protection and pollution prevention.It first received global endorsement as a management and developmental strategy at the highly …
To consolidate the concept of circular hydrometallurgical flowsheets, we present the 12 Principles that will boost sustainability: (1) regenerate reagents, (2) close water loops, …
Abstract. Arsenic contamination of groundwater has emerged as a significant challenge for the human right to water in India because of over 80% dependence on groundwater for drinking, particularly in the rural areas. In order to mitigate the arsenic menace and provide safe drinking water to the masses, government and non …
With the development of technology, the concepts of "green" and "sustainable" have gradually been popularized in all walks of life. With the continuous …
The challenge for the mining industry is to obtain enough production of arsenic to meet economic demands and provide a safe environment with zero arsenic emissions. Background Arsenic is the 20th most abundant component of the Earth's crust, and is widely distributed in rocks and soils, in natural waters, some mineral deposits, and in …
sustainable mining practices and improved operational outcomes in mineral processing plants. In this study, a 251 clustering-based method, Neighborhood …
Mineral waste can be defined as a material leftover from exploration, mining and quarrying operation that cannot find a productive use. It is the high-volume material that originates from the excavation and physical and chemical processing of a wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods [].The …
the management of mining waste in a way that in creases its value and reduces risk posed by the. waste. A new approach driven by circular economy as pirations and sustainable development ideals ...
The mining industry today faces a new set of environmental, social, economic, and political challenges. Despite efforts deployed by companies to improve their sustainable practices, and the proliferation of international initiatives aiming at enhanced sector management governance, mining is again being challenged. Centralized …
Arsenic (As), contamination in drinking groundwater resources is commonly environmental problem in many developing countries including Pakistan, with significant human health risk reports. In ...
Sustainable Development Framework for the mining sector with suitable benefit to the community affected by mining related operations should implement; …
MR system was established in the USA and mainly focused on open-pit mines (Xiao et al., 2021b).In 1977, the United States enacted the Surface Mining Control and Reclamation Act (Ruggles et al., 2021).Chapter one, Section 102, e) assures those adequate procedures to reclaim surface areas as contemporaneously as possible with …
Arsenic (As), cited as the most hazardous substance by the U.S. Agency for Toxic Substance and Disease Registry (ATSDR, 2005), is an ubiquitous metalloid which when ingested for prolonged periods cause extensive health effects leading to ultimate untimely death.Plants and microbes can help mitigate soil and groundwater As problem …
