Waste Characteristics. Mine waste may arise in a number of forms: as stripped soil and coarse, broken, partly weathered rock overburden in open cast or strip-mining operations; as unweathered development waste rock in underground mining; and as fine-grained tailings, the residuum of the process of comminution and mineral …

There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining. ... When it's no longer economical to operate an open-pit mine, it's commonly converted to a landfill or waste disposal site.
Ask the Chatbot a Question Ask the Chatbot a Question strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations …
The Sungun mine is a large porphyry copper mine with an extraction method of open pit mining (Yari et al., 2013), which causes major impacts on the surface biophysical characteristics such as land and landscape degradation, mass production of waste mineral extraction and loss of vegetation (Xiang et al., 2018). In the waste …
Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron . ore is the material from which the metal iron is produced.. The process of mining dates back to prehistoric times.. Prehistoric people first mined flint, which was ideal for tools and …
Waste is an unavoidable by-product of human activity, and rising living standards have led to increases in the quantity and complexity of generated waste (Rathi 2006).The rate of municipal solid waste (MSW) output will rise dramatically in the coming decades (Hoang et al. 2022; Naveenkumar et al. 2023).Handling and disposing of MSW …
Surface mining operations generate excessive waste rocks from overburden, footwall, and hanging wall. These huge waste rocks need to be removed carefully, transported and stacked by scientific and systematic manner at safe location. 4. Loss of production due to extreme summer and winter rain, and snow.
Surface mining is the main mining method in the mining industry. During the mining process, a large amount of soil and rock needs to be stripped to expose the ore body. The ratio of stripping volume to mining volume is called stripping ratio, which is an important indicator to measure the economic benefits of surface mining (unit: m 3 /m 3, …
Abstract Coal is the cheapest and thus the preferred energy source in developing countries. A huge volume of coal mine waste rock, which is known as overburden (OB), is generated due to the surface mining of coal. Due to convenience and the restricted ... Practical Applications The question of how to replace traditional …
Surface mine tailings are often combined with a binder in a small backfill factory before being transferred to subterranean stopes through gravity and/or pumping [175]. The amount of mining tailings that must be kept in tailings ponds is lessened as a result of this method [175]. It is possible to decrease the challenges associated with mine ...
Mining can adversely affect the quantity and quality of groundwater and surface water in mining areas (Bebbington and Williams 2008; Vidic et al. 2013), threatening the sustainability of water resources (Yang et al. 2013) and the public health of local residents (Li et al. 2016; Wu and Sun 2016).Ecological degradation and health …
In light of the gaps observed in the existing solid electro-electronic waste management, as highlighted by Xavier et al. (2023), Gaur et al. (2023), Erdiaw-Kwasie et al. (2024), the current study sets out to achieve the following specific objectives: 1) Scrutinize the state of the art of e-waste and urban mining practices, as documented in the ...
Surface mining; Classification of surface mining methods together with the desired parameters/ conditions suitable for their applications; Open pit mining; Classification of quarrying methods ...
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones …
Mining is an important industry, estimated to account for as much as 11% of global GDP and 109% of all greenhouse gas emissions. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments. Mining waste comes in several forms. It could be solid …
1. Introduction. In surface mining, soil and rock overlying or hosting a shallow ore deposit is physically removed to access the resource. Surface mining comprises different practices − strip mining, open-pit mining and mountaintop-removal mining − and accounts for more than 80% of ore mined each year (Ramani, …
Mining plays an essential role in resource-rich countries given that it constitutes a source of raw materials and incomes capable of contributing to the economic growth. However, with the intensive mechanisation of mining operations and the modernisation of the ore-processing technologies in view of increasing the …
Surface mining is a mining process where the rocks and soil overlying the mineral deposits are removed. It is often the preferred form of mining for most mining companies. This is because removing the terrain surface, …
Overburden removal frequently constitutes a large fraction, often the largest fraction, of solid "waste" associated with surface mining . A second source of solid wastes is the products that result from the processing of the ore. ... Depending on the waste characteristics and properties, a variety of environmental and health concerns may be ...
