We propose recommendations to enhance the environmental performances of mine tailings reprocessing strategies, such as switching to low-impact chemical alternatives and optimizing energy use.
Solid waste management is a critical issue worldwide. Effectively utilizing these solid waste resources presents a viable solution. This study focuses on Iron ore tailings (IOTs), a solid waste generated during iron ore processing, which can be used as supplementary cementitious materials (SCMs) but have low reactivity, hindering their large-scale application …
Mine tailings have historically been deposited in different ways, mainly focusing on the criteria of making transport, deposition, and storage as cost-effective as possible [2].
The tailings ponds (TPS) are mine facilities that store solid waste such as tailings (Kossoff et al., 2014; Tang et al., 2020).TPS has the characteristics of high potential energy and pollution, which make it one of the most important public hazards (Wang et al., 2022b; Xie et al., 2009).Since 1915, 257 tailings pond accidents have occurred with 2650 deaths and 250 …
The open slag piles, with residual heavy metals, have increasingly polluted surrounding environments and affected human health. Rainfall-facilitated leaching and seepage, alongside the physical weathering and biogeochemical reactions of tailings, can lead to the infiltration of heavy metals into water, soil, and the biosphere (Dong et al., 2024; Feng et al., 2024; He et al., 2023; …
The growing demand for lithium-ion batteries (LIBs) in smartphones, electric vehicles (EVs), and other energy storage devices should be correlated with their environmental impacts from production to usage and recycling. As the use of LIBs grows, so does the number of waste LIBs, demanding a recycling procedure as a sustainable resource and safer for the …
Iron ore tailings (IOT)—industrial byproducts—are un-floating minerals in the flotation process of raw ore. Their large stockpiles and low utilization rates have become pressing challenges. This study provides a cleaner production solution for the potential usage of IOT as ecofriendly fine aggregates in the cementitious composite. The mechanical properties, …
Purpose Large stocks of many kinds of zinc smelting solid waste have been generated; moreover, the disposal process consumes high amounts of energy and takes low output rate of metal resources, which seriously endangers regional ecological environment and human health. The purpose of this study is to compare the environmental impact of the …
UNEP defines Environmental Impact Assessment (EIA) as a tool used to identify the environmental, social and economic impacts of a project prior to decision-making. It aims to predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment ...
Economic potential and environmental impact of metal recovery from copper slag flotation tailings ... This study investigated the potential of copper slag tailings alongside global metal supply and demand dynamics. It has been emphasized that, such as copper slag, slag tailings can be a new potential resource for global base metals, considering ...
Shaanxi Province is located in the most important molybdenum ore district in the world, but a lot of molybdenum tailings have been released, polluting the environment and wasting resources seriously. Taking eleven tailing …
The utilization of self-consolidating backfill material in mine filling is widespread, with both practical engineering applications and theoretical studies contributing valuable foundational parameters and experiences [6], [7].Research focused on the preparation of self-consolidating backfill material has predominantly involved numerical simulations of cement …
Tailings containment dam failures cause severe environmental, social, and economic impacts. Analyzing past occurrences allows society and decision-makers to improve storage facility safety. This study presents an overview of tailings dam failures, exploring historical aspects and environmental consequences. Two methodological strategies were used: 1. An …
Paste backfilling is an incipient underground mine backfill technology in India. It facilitates maximum use of mill tailings with enhanced stability of the underground workings and minimises rehandling of water, as …
Highway construction is time consuming and complicated. Various environmental issues can be encountered during this process. Therefore, it is necessary to assess the impact of ecologic environment in highway construction. However, the traditional assessment approaches paid more attention to the environmental factors rather than the ecological problems, and the …
A conceptual case study for the disposal of gold tailings in Western Australia as a slurry, or as filtered tailings, was considered. The environmental impacts of each option were assessed ...
Environmental impact of 143 tailings storage facility (TSF) failures in China has been analyzed. Approximately 75 % of the TSF failures discharged tailings into aquatic …
There are various processes in management of mine tailings such as minimizing tailings production and increasing tailings reuse, adoption of a risk-based approach and …
It provides a scientific and technological basis for the decision-making of environmental authorities, with a focus on double-checking the potential environmental impacts that may exist in proposed projects from the perspectives of experts and stakeholders. ... Environmental impact assessment of projects in the People's Republic of China: New ...
In this study, we focus on inorganic materials, such as tailings, smelting slag, coal ash, and desulphurization gypsum, which produce more than 10 million tons per year and …
The potential uses of copper mine tailings and steel slag need to be explored and the negative impact of mine tailings should be reduced by exploring potential uses of these waste materials in the ...
The research framework in this paper can provide reference for environmental impact assessment of other types of bulk industrial solid waste and provide ... (USGS, 2017). Tailings are "waste" slag left after extracting useful substances or elements from raw ore from metal or non-metal mines. ... this study quantitatively assessed ...
Environmental Impact Assessment (EIA) is a systematic process in civil engineering to evaluate the potential environmental effects of proposed projects, plans, or developments. The primary purpose of EIA is to ensure that any undertaking that may impact the environment is thoroughly assessed before implementation.
What Are the Dangers of Tailings? Mine tailings pose significant environmental hazards that require careful management to prevent long-term ecological damage. These dangers stem from various sources, including water contamination, soil degradation, air pollution, and catastrophic dam failures. Environmental Damage from Mine Tailings
Environmental impact of 143 tailings storage facility (TSF) failures in China has been analyzed. ... The 1988 Suyugou TSF failure incident in Shaanxi Province resulted in the most extensive downstream pollution, with contamination reportedly extending for approximately 440 km of river channels, in addition to the damage or destruction of 132 ...
Our environmental impact assessment of tailings resource utilization can provide data support for developing relevant standards and enhance credibility for resourceized …
In order to build green mines, goaf is often filled, supported, and sealed with a high-water material to eliminate a series of environmental problems and safety hazards caused by goaf.
Sulfidic copper tailings (STs) is a byproduct generated from mineral processing activities. To address this environmental burden, calcium aluminate cement (CAC) was used to utilize STs as cementitious materials. The influence of STs on the hydration process, mechanical properties and life-cycle assessment of STs blended CAC were investigated.
A high-level social and environmental assessment is then undertaken. This involves the creation of a hypothetical flow path from a tailings dam which is then buffered to provide a theoretical impact.
