Abstract:

Abstract Purpose The gold routes satisfying the global gold supply are mining (74%), recycling of high-value gold (23%), and electronic scraps (3%). Besides its applications in the investment, jewelry, and industrial sector, gold also has a bad image. The gold production in industrial as well as artisanal and small-scale mines creates negative impacts such as resource depletion, extensive chemical use, toxic emissions, high energy consumption, and social concerns that are of great importance. On the other hand, almost all gold is recycled and has historically always been. In common life cycle

Abstract:

The mining industry is a significant asset to the development of countries. Ghana, Africa’s second-largest gold producer, has benefited from gold mining as the sector generates about 90% of the country’s total exports. Just like all industries, mining is associated with benefits and risks to indigenes and the host environment. Small-scale miners are mostly accused in Ghana of being environmentally disruptive, due to their modes of operations. As a result, this paper seeks to assess the environmental impacts of large-scale gold mining with the Nzema Mines in Ellembelle as a case study. The stud

Abstract:

Primary artisanal mercury (Hg) mining in Mexico continues to proliferate unabated, while official Hg exports have declined in recent years amid speculation of a rising black market trade. In this paper, an assessment of primary Hg mining in Mexico was conducted, with a focus on four sites in Querétaro State. Atmospheric Hg concentrations were measured at two of those sites. In addition, trade data was examined, including Hg exports from Mexico and imports by countries that have a large artisanal gold mining (AGM) sector. Results showed that while annual Hg production in Mexico has ramped up in

AbstractThe local effects of mining might simply come and go with mine production. In this paper we revisit Aragón and Rud's (2013) study of the Yanacocha mine, frequently cited to account for local economic effects and backward linkages, but we offer a more nuanced interpretation: first, effects fade with the mine exhaustion; and second, impacts are the result of consumption boom-and-bust dynamics. While we find it more conceptually accurate to reserve the concept of backward linkages for effects of a productive nature, our evidence reveals that unskilled services is the one sector that benef

Abstract:

By the 1930s, silicosis – a debilitating lung disease caused by the inhalation of silica dust – had reached epidemic proportions among miners in the gold-producing Porcupine region of northern Ontario. In response, industrial doctors at the McIntyre Mine began to test aluminum powder as a possible prophylactic against the effects of silica dust. In 1944, the newly created McIntyre Research Foundation began distributing aluminum powder throughout Canada and exported this new therapy to mines across the globe. The practice continued until the 1980s despite a failure to replicate preventative eff

Mining, in addition to other human activities and natural phenomena, has repeatedly reshaped the landscapes of the Peruvian Andes. Long-standing, significantly modified and new Andean landscapes have resulted in a complex reading of the ‘land as palimpsest’ (Corboz, 1983). In recent decades, large-scale modern mining has disturbed headwater landscapes and broader Andean ecologies, as exemplified in Cajamarca’s gold mines.

Abstract:

Mining wastes containing sulfide minerals can generate contaminated waters as acid mine drainage (AMD) and contaminated neutral drainage (CND). This occurs when such minerals are exposed to oxygen and water. Nowadays, mineralogical work—when it is done—is independently and differentially done according to the needs of the exploration, geotechnics, metallurgy or environment department, at different stages in the mine development process. Moreover, environmental impact assessments (EIA) are realized late in the process and rarely contain pertinent mineralogical characterization on ores and waste

Abstract:

A common challenge faced in underground hardrock mines worldwide is post mining-induced seismicity, as the events have been quite disastrous, causing risk to the structures and lives. In the recent years, many of the worked out mining areas are slowly getting populated and in due course of time shall be posing environmental threat to the people residing above and to the surface structures like sudden void formations or sudden ground collapse becoming visible on the surface. Worked out or closed mines have most of the time shown existence of post mining-induced seismicity signatures. Some of th

Abstract:

Mining settlements are typically portrayed as either consisting of purpose-built housing constructed by mining companies to house their workers, or as temporary makeshift shelters built by miners working informally and inhabited by male migrants who live dangerously and develop little attachment to these places. This paper contributes to these debates on the social and material dynamics occurring in mining settlements, focusing on those with urban rather than rural characteristics, by highlighting how misconceived these archetypal portrayals are in the Ghanaian context.

ABSTRACT: Hardrock mining companies contribute positively to the U.S. economy. However, they also cause serious degradation to the surrounding environment. According to the Environmental Protection Agency, hardrock mining companies are among the greatest polluters in the United States. Mining companies are responsible for satisfying legal obligations arising under environmental laws that include cleanup and exit costs for all mines shut down. These environmental liabilities are called asset retirement obligations and under FAS No. 143, U.S. mining operators are required to recognize their asse

Abstract:

The pervasive importance of gold mining in modern South Africa has become embedded in South African historiography. Despite this, little research has been done to ascertain its impact on the other major sector of the economy, agriculture.The gold mines had a profound effect upon one particular branch of agriculture – beef farming. The mines purchased large amounts of beef and were able to use their buying power to confront beef farmers in the marketplace. In the recession following the First World War, the mines were caught in a profitability crisis that was to lead to the Rand Revolt in 1922.

Abstract:

Historic gold and coal mines in the same catchment near Reefton, New Zealand allow comparison of environmental effects of the different mines in the same climate and topography. Gold mine discharge waters (neutral pH) deposit hydrated iron oxide (HFO) abundantly at mine entrances, whereas coal mine discharge waters (low pH) precipitate HFO tens to hundreds of metres downstream as pH rises. Waters leaving historic mines have up to 59 mg L−1 dissolved arsenic, and HFO at gold mines has up to 20 wt% arsenic. Coal mine discharge waters have low dissolved arsenic (typically near 0.01 mg L−1) and HF

Abstract:

Simulations of open pit mines dewatering, their flooding, and environmental impact assessment are performed using groundwater flow models. They must take into consideration both regional groundwater conditions and the specificity of mine dewatering operations. This method has been used to a great extent in Polish opencast mines since the 1970s. However, the use of numerical models in mining hydrogeology has certain limitations resulting from existing uncertainties as to the assumed hydrogeological parameters and boundary conditions. They include shortcomings in the identification of hydrogeolo

AbstractThe increase in the international price of commodities after the international financial crisis in 2008 produced a gold rush in the Colombian economy, making legal and illegal mining a very profitable and attractive business. The increase in the illegal exploitation of metals like gold has exacerbated violence in municipalities with an abundance of such minerals. Gold is believed to be a new engine in the Colombian conflict.
