The use of serpentine rock in concrete can provide a number of benefits. For example, it is a durable and weather-resistant material that can withstand freeze–thaw cycles and exposure to salt and chemicals. Additionally, it is relatively lightweight and can be used to reduce the weight of concrete structures.

Large-scale closure of coal mines is required for China to achieve carbon neutrality. However, what this means for methane emissions, particularly for abandoned mine methane (AMM), is highly ...

A scoping review of literature, indexed in scientic journals and other sources. Published docu- ments from 2008 to 2019, about worker's health at Chilean copper mines. e aim consisted of

To maintain high-level economic development, protect the ecological environment, and achieve carbon peaking and carbon neutrality goals, the construction of green mines has become a critical issue in China. In this study, the importance of mineral resources to human society is discussed, and the construction experiences and …

Introduction. Mineral wealth is an important asset that can be used to stimulate or enhance economic growth and spur infrastructure development, including the building of schools, hospitals and road networks.1 Mining has played a substantial role in the development of Ghana, which is second only to South Africa in terms of gold …

The systematic literature review method is widely recognized for its robustness and effectiveness in identifying, gathering, and synthesizing relevant information from a variety of sources (Wibowo et al., 2023c). By employing a systematic approach, this method ensures that the review process is transparent, rigorous, and replicable.

2.0 Literature Review . 2.1 Introduction . Crushing plants usually consist of set of machines that are put together to form a process to gradually reduce the size of the processed material until the desired output size is met. The machines include the following: 1. Size reduction machine( crushers) 2. Separation Machines ( screens) 3.

1. Introduction. Ecological restoration of mining areas refers to the restoration of ecological problems such as geological hazards, land damage and vegetation damage caused by mining activities by relying on natural forces or through artificial intervention, so as to stabilize the geological environment, reclaim the damaged land, and restore and …

The present paper aims to provide a comprehensive literature review of all aspects of technical, economic and sustainable development of in-pit crushing systems along with a statistical analysis of the systems since 1956 to the present. The paper also presents the scope of future research and examines defects and flaws in the design and ...

However, 7% of heat-related accidents in underground mines were reported to occur at an unknown time of the day. Fig. 1. Number of heat-related accidents in the mining industry (surface and underground) by level of experience: beginner (0–1 year), intermediate (1–5 years), advanced (5–15 years), and expert (> 15 years).

Sewage/Wastewater Treatment Literature Review. ... commonly referred to as "fracking," is a technique used by the oil and gas industry to mine hydrocarbons trapped deep beneath the Earth's surface ...

Acid mine drainage (AMD) is the biggest environmental problem of water related to the mining industry in many countries. Recently, coal mining and mineral mining industries use various AMD treatment systems. The main problem, however, is the very expensive and long retention times for treatment of AMD. For this reason, biosorption …

1. Introduction. Energy and mineral resources have always been a hot topic for all countries around the world. The exploitation of minerals has promoted the world economy and people's living standards widely, but it has also brought serious damage to the environment.

We used three sources of information in our review: (1) the peer-reviewed, published literature, (2) the Programmatic Environmental Impact Statement (PEIS) on MTM–VF in Appalachia and its associated appendices (U.S. EPA, 2003, U.S. EPA, 2005) and (3) published, peer-reviewed reports by government and state agencies.This review …

Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments. It reached 7 billion tonnes of mine tailings generated yearly worldwide, and 19 billion solid tailings will be accumulated by …

The data obtained were compared with literature data available. Except for samples collected near mines and smelting plants, where Cd, Pb, and Zn concentrations were up to 15 times higher, in all other cases, no differences were observed with respect to samples from rural areas, except for Pb concentration, which was 3 times higher in urban areas.

This review has revealed that there is a paucity of studies on mining-related air pollution in Zambia. The main identified air pollutants were SO 2 and particulate matter (PM), both fine and ultrafine (PM 10, PM 5.0, PM 2.5 and PM 0.1 ).

However, three recommendations seem apt in the light of the literature review presented in this work. First, mine engineers and managers should choose energy efficiency programs based on good estimates of the return on investment. There are many options to choose from in any attempt to improve on a mine's energy efficiency. For the …

The end product is a nickel-copper-cobalt-PGM concentrate, which is sold to Jinchuan Group for smelting. Albidon recorded its first revenue from the sale of Munali concentrate in October 2008. The mine and processing plant deployed at the project has a capacity of 80,000tpm. The water supply for the project comes partly from an on-site …

These abandoned mine land usually suffer from deficient plant nutrient (N, P, K), toxic chemicals, poor physical structure, and extreme soil pH. Furthermore, mining causes adverse effects on human life. ... the writing of this review was necessitated by the fact that after a careful survey of several literature platforms, we could not find a ...

Coal mine pollution is a serious threat to the mine safe production and occupational health of miners. Chemical dust suppression can effectively reduce the concentration of coal dust and suppress the re-entrainment of dust. This paper discusses the research progress of three kinds of traditional dust suppressants: the wetting-type, …

Moreover, the two mine types constituting the bulk of the literature (bauxite and mineral sands) have less pollution risks than other mining industries (e.g., gold cyanide-bearing tailings, Donato et al., 2007; and coal acid drainage, Harries, 1997), further biasing the literature. As a consequence of these two biases, the results of this ...

Methods. A literature review was performed where articles were sought in MEDLINE medical database via PubMed using the search terms: "dry ice poisoning," "carbon dioxide poisoning," "CO 2 poisoning," "carbon dioxide intoxication," and "CO 2 intoxication." The references of the articles that were found were further evaluated to …

The scientific literature on mining and biodiversity is also scarce, with less than 1% of papers in leading conservation journals referring to mining-related threats (electronic supplementary material, S1). ... given that site preparation for mine expansion and waste management is a destructive process, ... 2015 A review of corporate goals of ...

Based on the literature and information review about the mentioned topic, the following summary can be given: all the reference lists of the included papers, information gathering from consultants, electronic database and grey literature searches, reveal that mines are widely using the traditional or "old style" of mine water treatment …

The United States has witnessed a concerning surge in the incidence of diseases like Coal Workers' Pneumoconiosis (CWP), despite numerous efforts aimed at prevention. This study delves into the realm of respiratory health by investigating the deposition of dust particles within the respiratory tract and lungs. By analyzing particles …

Water treatment for elevated metal levels and acidity is a common outcome of acid mine drainage. The effectiveness and feasibility of water treatment is highly variable depending on the treatments employed and unique site characteristics. Water treatment installations may include both passive and active systems.
