Human activity is considered to be the major source of pollution and contamination by potentially toxic metals in soils. Among the various causes of this type of contamination we can mention mining and the processing of metals, which are linked to several environmental problems (e.g. acid mine drainage, impact on the landscape, and …Web

Environmental issues have become important, if not critical, factors in the success of proposed mining projects worldwide. In an ongoing and intense public debate about mining and its perceived environmental impacts, the mining industry points out that there are many examples of environmentally responsible mining currently being carried …Web

In some cases, Sb mobility is limited by its adsorption and incorporation into Fe (oxyhydr)oxides. At higher Sb concentrations, precipitation of Sb secondary hosts such as tripuhyite (FeSbO 4, relatively insoluble) and brandholzite (Mg[Sb(OH) 6] 2 · 6H 2 O, highly soluble) influence Sb concentrations in water associated with mine waste ...Web

Abstract. Mine planning is the process that determines the way in which an ore deposit will be mined over the life of a mining operation. It necessarily draws on everything that planning engineers believe will determine the ultimate success of the proposed mine and uses as its foundation all of the geology-related data on the deposit.Web

We further process these traces by applying standard seismic-exploration processing routines to obtain zero-offset seismic sections along directions of interest. …Web

Mining-related environmental signatures are defined here as the concentrations and chemical, mineralogical, or biological forms of these metals and chemicals prior to mitigation or remediation in mining and milling wastes, mine waters, mineral processing solutions and byproducts, and smelter emissions and byproducts.Web

Overview. The rare earth elements (REEs) are comprised of the lanthanide elements plus scandium and yttrium, which have similar physical properties and are often found in the same ores and deposits. Specifically, REEs include the light REEs (LREEs) such as lanthanum, cerium, praseodymium, neodymium, samarium, europium, and the heavy …Web

The Yilgarn craton is one of the world's major nickel provinces, containing 31.5 million tonnes (Mt) of Nimetal with an in situ value of about $350 billion on a pre-mining basis, amounting to 13.6 percent of the world'scurrently known Ni resources. This entire resource inventory has been discovered since 1966.Web

Sampling points marked with S plus numbers are shown in Fig. 1. The S1 sampling site was located between the mining area and the river. Soil samples S2, S3, S4, and S5 were collected within the proximity of the Sb smelter. S6, S7 and S8 were located around the mine, downstream of the Lianxi River andWeb

Abstract. Postdevelopment studies show that, once in operation, about 70% of mines perform below the prediction of their feasibility studies, with underperformance usually caused by deficiencies in the collection of primarily geology related data prior to designing the mine and planning its operation. A major reason for these deficiencies is ...Web

There are some problems in the implementation process, such as limited by site conditions, large quantities, and high labor intensity [11–13]. A large number of practices show that backfilling mining can effectively control overburden deformation, reduce surface subsidence, and prevent rockburst disasters.Web

The unstructured data do not have a predefined schema and usually require data processing to yield semantic information and relational data (Sint et al., 2009; Li et al., 2015), such as satellite imagery, geoscience literature, scanned geological map, and image.

This process continued until the end of mining. Relatively high tailgate convergence of 1700 mm, 2100 mm, and 2300 mm was measured at the face advance of 622 m, 664 m, and 900 m, respectively, while a smaller convergence of 300 mm, 400 mm, and 700 mm was measured at 350 m, 741 m, and 944 m (Figure 4 ).Web

There were also changes in the location of production in response to geopolitical forces, the depletion of ore reserves, and the changing economics of extraction and processing. The number of mines contracted, especially during the 1990s, and the scale of mining operations was increased in order to achieve the requisite cost savings.Web

Test mining of Fe–Mn nodules and seafloor massive sulfides has already been undertaken. However, full-scale deep-ocean mining systems, including ship-to-ship ore transfer and equipment reliability in ~5,000 m water depths, still require field testing .

Metal and mineral deposits are, in fact, geochemical anomalies and, as such, applied geochemistry plays a critical role throughout the mineral resources value chain, from early stage exploration to mine closure. The fundamentals of element mobility (i.e. transport and fixation) in the near-surface environment are used by geochemists to detect ...Web

Modern large-scale gold mining by cyanide leaching of low-grade ore generates a large volume of process fluids. Reduction and disposal of these fluids presents unique challenges. Leaching solutions, tailings dewatering, and even postmining pit lakes must be managed both in the immediate short term and over decades or longer.Web

This is only achieved when geologists, metallurgists, and mining and environmental engineers jointly assess the results of metallurgical characterization. This requirement is examined here, albeit for only two of the three metallurgical ore-processing activities—comminution and mineral separation.Web

Abstract. The role of geology in advanced mining studies, such as feasibility studies, is commonly dwarfed by the technical inputs from mining, metallurgical, and social license issues. Understanding and planning for geologic risk in the feasibility process is often overlooked for the higher-profile aspects required to establish an ore reserve.Web
