2020-5-8 Mining has played a part in the economic development of developed countries such as the USA, Canada and Australia. However, the mining economic growth connection varies considerably from that claimed in the historical analogy reasoning. It is not evident that these countries’ historical experience applies to modern developing nations due to modifications in the nature of the world economy.
The mining, processing and utilisation of metals dates back to Roman times and earlier with extensive developments in many parts of the world by the eighteenth and nineteenth centuries. Many mineralised areas are no longer worked leaving a legacy of dereliction and contaminated land and drainage.
2020-2-3 NEW YORK, NY, USA, 3 February 2020 —Released today, the 12th annual edition of Deloitte Global’s mining report, Tracking the Trends, explores key trends facing mining companies in their ongoing pursuit of productivity, financial discipline, operational excellence, and sustainable growth. “Mining
2019-7-23 Abstract. This paper reviews socio-economic and political impacts of the extractive industry based on a global literature review. It reveals 27 different impacts (23 socio-economics and 4 political) associated with the industry.
A post mining site. environment created in the aftermath of opencast mining is unable to support biomass development in the region (Figure 5). Illegal and uncontrolled mining in the region is a big issue of concern. In an inspection of Directorate of Mines Safety, Varanasi, in August, 2014 in silica sand mines of
2012-12-11 Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining

2020-7-14 Mining and quarrying for minor minerals impart significant economic, environmental and social impacts in and around the affected areas. The problem is severe in the small river catchments as the effective area available for assimilating negative impacts of the activity is minimal, compared to large river basins. To address these issues, an investigation has been carried out in two river basins

The determination of the impacts of marble mining on the environment in Igarra was carried out via the analysis of soil and water samples as geological medium. Seven soil samples, ten water samples and five rock samples were collected. The samples collected were subjected to petro-graphic and geochemical analysis. The mean concentration of metals in soil from Ekpeshi were Cd (3.254 mg/kg), Co
Tanzanite is the blue vanadium-bearing variety of zoisite. The only known source of gem-quality tanzanite, to date, is the Merelani area of northeastern Tanzania, a structurally complex region consisting of granulite facies metacarbonate and metasilicate rocks
High concentration of fluoride in the groundwater is observed to be associated with granitic aquifers as well as near phosphate mines around the globe. The present work is a hydrogeological study of the ground water of Beldih phosphate mines in India. Being located in the Singhbhum shear zone the area has a complex tectonic history and is dominated by phosphate, alkali granites, amphibolites

2008-8-26 Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.
2020-4-14 Traditional forms of mining can be unsafe for workers. Fires and collapses can be deadly, and the health effects of mining can be devastating. Others, however, object to mining in general. Because coal and oil release carbon dioxide when used as fuel, some argue that mining exacerbates global
